blitz67 Posted November 20, 2015 Share #1 Posted November 20, 2015 I purchased this online from a local auction company, I didn't think I would get it, but it went very cheap and I am very happy to have this. This is a pitot tube off of a P-40 Warhawk, I assume it was destroyed on Dec 7th and the soldier took it as a souvenir, his name is Maynard Morris, hope you all like it!

firefighter Posted November 20, 2015 Share #8 Posted November 20, 2015 I am not familiar with these items, but why would it be marked with JAPAN patent number? Link to comment Share on other sites More sharing options...
doyler Posted November 20, 2015 Share #9 Posted November 20, 2015 Thats intresting. Your last marking is TH...Territory of Hawaii. This is often how Hawaii is reffered to prior to becoming a state. Link to comment Share on other sites More sharing options...

72psb Posted November 20, 2015 Share #11 Posted November 20, 2015 The pitot tube is a home for spiders. Not really,it provides air for the instruments.Gyro I believe,maybe wrong. Link to comment Share on other sites More sharing options...

phantomfixer Posted November 20, 2015 Share #13 Posted November 20, 2015 yep provides for airspeed, verticle speed and altimeter...tube is heated to prevent icing Japan patent caught my eye too...but heck we were not at war with them in the mid to late 30s when the P40 came out...and maybe a carry over of inventory from the P-36??? anyway neat piece of history Link to comment Share on other sites More sharing options...

Longbranch Posted November 23, 2015 Share #16 Posted November 23, 2015 That's a neat pitot tube with some fascinating history behind it. The patent # matches up to a Kollsman Instruments design, which was created by Paul Kollsman (a famous inventor of aviation instruments and related items). In 1939/40, he sold his company to the Square D Company, which is listed as the company that was originally assigned the patent. The "Japan Pat." likely references a separate patent given for this pitot tube so it could be sold in the Japanese market. Obviously this would not have been possible after the US declared war against Japan. Kollsman pitot tubes seem to have been commonly used on WW2 US aircraft. You can actually find some NOS Kollsman pitot tubes purchased by the US Navy during 1942-1945, which look slightly different from this one (and without the Japanese patent info). It is certainly possible this is a pre-1942 Kollsman pitot tube as fitted to a 1940/41 production Curtiss P-40. Since this part was made during or after 1940, it was not "left over stock" from P-36 production. Link to comment Share on other sites More sharing options...
phantomfixer Posted November 23, 2015 Share #17 Posted November 23, 2015 That is good info on the pitot tube...good to know the piece is original P-40 equipment...and glad to know it did not come from left over inventory... Link to comment Share on other sites More sharing options...
