Appreciated folks! Thanks

Hello. Saw that on ebay as well. Nice that it is a Cairo retailed pith helmet. I though the name and way it was written was American and perhaps the badge was added. There was a William Owen Pelkey that was an American that served in the R.N.W.M.P. and there is a Canadian military attestation form for him on-line dated 1917. I did not find him in the London Gazette which might indicate he was not part of the British Armed Forces (British officers will typically be mentioned there). These "Bombay bowlers" were popular with American CBI officers as well and there were some that came through Cairo. You might try the American angle. He might have become an officer and served in the CBI theater with and American unit. I took the number as 0-483281. British officers didn't seem to write their service numbers in their uniform items very often in my experience and I collect British militaria. 

Very nice! Love the commendation text and document; missing his commendation with ribbon on his bar.   Kurt

I like your panel line pin wash. BTW, what scale is this? 

Franc - Sorry for the slow reply, but as for the above post, I just saw this thread.   You 477 knife is an abberation - whether the 9 has worn down or been sanded/polished to look like a 7 or possibly the stamp broke and left a 9 that looks like a seven.  A clear picture of the stamp would help decide which.   Patent 1967477 was for a water gauge illumination device.

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.
