Hello, I got this yesterday and I looked it up on Google Images and it says its a Aiming Circle used for surveying for artillery and topography. Could this one have been used the WWII? How long did they use this model? Who would be the manufacturer? The serial number is 3001 and another number "8211649" also appears. Thanks John  

. Assembling a wooden Jeep day    Two of us started assembling the pieces we cut out on Saturday, we are probably achieved about forty percent of the complete  build, we have a few more days assembly work and then the ladies doing the crochet and knitting panels will come and cover it next week with their handwork.    Not that our build is anything but amateurish and we are not setting any precedent as wooden Jeep bodies were tested during WWII to conserve metal, after all the British Mosquito aircraft of WWIi was a flying wonder and exceeded all expectations           Norman D.

marshllj- No they are mini thanks for looking and commenting?

Whoever beat me on this one, Congratulations   USS TRUXTUN (DDG-103)  

I thought I would post this WWII chit that belonged to my Dad.  My dad,  Lt Robert T Cronau, Jr, flew in the CBI theater in the First Combat Cargo group during May and June of 1945 and later in the Philippines.  He received the Distinguished Flying Cross for his CBI service.  I found this chit and 10 of the double-sided survival maps in his things.  Haven't figured out where to post those yet.  I remember "playing" with the maps when I was little!  I believe all of them are printed on Rayon.  The maps have a range of dates on them from 1943-1945. This particular chit seems to have more languages that many that I have seen.  I believe it is authentic but it has no serial numbers or other markings.

I'll some pics tomorow.

Full size? 

Rooster-No they are not real. but thanks for asking. No offense taken. 

So the upper part of the slot is 1/4", the "turn" is 3/8", overall slot length is 1 5/8" I didn't see any evidence of a locking ring.  There is kind of a matching divot on each side of the top of the socket.  I don't know if that is significant or just the way it rusted.
