Myles Posted March 18, 2011 Share #1 Posted March 18, 2011 I have a Wittnauer compass that is identical to a USAAF compass. It has the U.S. marked on the front cover, but it does not have the part number on the reverse side. The odd thing is that the arrow points due south. It is not just a little off, but a full 180 degrees, and points perfectly due south. Was this compass manufactured this way? Could something have happened to it to reverse the polarity? Could it have been made this way to confuse the enemy in case it fell into enemy hands? :think: Any observations, ideas or conjecture will be welcome. Thanks for any coments, Myles Link to comment Share on other sites More sharing options...
Jack's Son Posted March 18, 2011 Share #2 Posted March 18, 2011 Myles, Welcome to the forum! While I don't have the answer to your question, I'm sure someone will happen along who does!! Enjoy your time with us. Link to comment Share on other sites More sharing options...
rrobertscv Posted March 18, 2011 Share #3 Posted March 18, 2011 My first thought. If your over 65 that could be why your compass points south!!! LOL Welcome to the forum, I'm sure someone will chime in with the real answer shortly. Just wanted to welcome you on board!! Link to comment Share on other sites More sharing options...
316th FS 324th FG Posted March 18, 2011 Share #4 Posted March 18, 2011 Basically, someone put it to close to a magnet and reversed its polarity. Not uncommon but annoying. Happens a lot in our scout troop. I have heard you can fix it, but havent tried myself. Link to comment Share on other sites More sharing options...

Just put the magnet on the north side is what i did to fix it.Keenan Thanks to everyone for your comments. Would the north side have been demagnetized, or would the south end have been magnetized stronger? I would assume that if I took a bar magnet that one end of it would repel the north end, and the other end would attract it. Or am I thinking too much and just need to puta horseshoe magnet on the north side? I think maybe I will leave it alone for now, until I find out some more about it.

artu44 Posted March 20, 2011 Share #8 Posted March 20, 2011 Shame on you guys!!!!!!! You never served in a mortar or artillery unit. Compass often are read through an optical devioe (mirror or prism or lens) aiming to a direction so you have to invert the letters N and S (not the earh poles) on your compass if you want to read it correctly. Check if your compass was repaired replacing original needle with another from above compasses or if the lid can act as mirror Link to comment Share on other sites More sharing options...

Myles Posted March 21, 2011 Author Share #11 Posted March 21, 2011 Cause itswarmer there.....sorry Arturo, That is an interesting idea, and I imagine that the inside of the lid would work as a mirror if it was polished enough. I have cleaned the compass, but I didn't try to polish it that much. I was afraid of over doing it and removing any nickel or silver plating [whichever it may have]. Also, it is a marching compass in the style of a pocketwatch, so I think an artillery man wouldn't bother going to that trouble. I purchased the compass several years ago in a flea market. It was in a shoebox with a bunch of junk. It is possible that a kid had it and played with it with a magnet. I went to a gun, knife, and militaria show in Harrisburg Pa. today, hoping to find another compass like this one to either buy, or at least compare it to, but I had no luck. I found only two compasses in the whole show. One was a WW1 marching compass, {just the outer case, no guts, and very beat up} and the other was a 1999 tritium lensatic compass, unissued with pouch for $55.00. There was some vintage field gear, but a lot of newer stuff, and reproductions. It cost me a fortune [in gasoline], parking, [i don't ever remember having to pay to park for a gun show] and the entry fee. I spent a lot of time driving, and walking around, and I didn't find anything to spend my money on Myles Link to comment Share on other sites More sharing options...

I always thought it was so one could use it to shave in the field. Link to comment Share on other sites More sharing options...

Obviously the pocket compass is made just for orienting a map and find a more-or-less direction. If your compass point exactly to the south, the only decent thinking is that worker inverted the needle during its magnetization process and nobody noticed it. BTW my old 1917 Usanite point North. I like a lot compasses and I think I have a quite complete collection from 1918-1945. You can use pics as reference for your next purchase.

artu44 Posted March 21, 2011 Share #14 Posted March 21, 2011 Here you can see the swiss mirror design compared with the brit primatic one. The mirror compass hasn't a needle (the entire dial rotates) and S and N are inverted to be corerct in the mirror. The prismatic has correct directions but dial inverted to read correct degrees in the prism. Link to comment Share on other sites More sharing options...

I would like to collect more compasses, but I have to find them first! For some reason I just don't seem to run accross them very much, and when I do they are cheap knockoffs, or something you would get for a kid. I have looked around the internet, and I believe the others are correct in that my compass was damaged by being too close to a magnet. Somewhere burried in all my junk I have a bar magnet, If I find it I may try to correct the problem with my Wittnauer. Myles Link to comment Share on other sites More sharing options...

Mike Woodall Posted September 9, 2020 Share #24 Posted September 9, 2020 I have a Wittnauer US pocket compass that points South instead of North. I would like to have it point North. Someone said that they used a magnet to reverse the direction of their compass. Please let me know how to do that. I can't find a repairman to deal with a pocket compass. Thanks.

dustin Posted September 9, 2020 Share #25 Posted September 9, 2020 As a side note to the discussion, the manufacturers (Wittnauer) part number on on the back is irrelevant to being USAAF procured. Both types with and without can be found in NOS boxes. Link to comment Share on other sites More sharing options...
