I found a photo on Worthpoint of a similar propeller pin with an Eglin Field center device on it.  That one was still on an original Smilo card.   I have also seen a wing like Patrick's that had an Shaw Field center device on it (photo below also from Worthpoint), and I have one with just an AAF winged-star center device.   I believe these were all souvenir pins sold at PXs around the country.  Smaller 1-1/2" souvenir wing pins with the same attached devices were also made

John, sorry for the slow reply but I just saw this post -   The knife itself is a pre-WW2 G46-4-1/2.  Made from 1931 to 1941.  This one was most likely made in 1940 to 1940.  The earlier versions had multiple gray/black colored fiber disks, not just "plain" leather.   The "date code" letter is an obvious add-on for 3 reasons.   First - no model number.  ALL date coded Westerns include the model number.  No exceptions. Second - a date code, on fixed blades, is always the 3rd line of the stamp, except for some models of year code I and J. Third - a date code letter never had a period,   The stamp chart has several errors. Or at the least, it is very incomplete.   The stamp should include the patent number, or at least a reference to it, which was included on all fixed blades that utilized the bifurcated tang construction from 1931 to 1953.  1931-1932 PAT. APPL'D FOR   1932-1933  PAT. PEND. 1933>>>  PATENTED or PAT'D or PAT 1,967,479

trying to track down Colonel W. Owen Pelkey Unit No. 0483281, of the Royal Warwickshire Regiment. Assuming he was in Egypt at time of Alamein in 1942 but could have been post WW2 also.

Excellent Grouping and presentation. Thank you for posting.

I have a USN group to a VB-136 pilot interned there. 

This is a good thread on these belts. Tim    

I first read the book "30 seconds over Tokyo" in grade school. The main crew in the book crashed on a beach and the pilot survived the crash but lost his leg and was  scared up badly in the face. In the attached clip from the movie.. I believe Van Johnson plays the Pilot of that B-25 as portrayed in the book.   That took a lot of guts, to go on a one way mission. This is a 14 minute clip from the movie.      

Thats a great helmet!!! Congratulations.... !!!
