Prop tip ID help…have the number

Dear prop gurus – just cleaning out my office and found a prop tip i picked up years ago, black, yellow tip, wooden, covered with that plasticky stuff ith a clear strip of plastic/paxolin on the ‘leading edge’ of the prop –

Number on it reads JP134838

Before I put it on ebay as belonging to Amelia Earhart/Gunther Rall/Dambuster of your choice for a squillion pounds, I wonder if anyone can tell me wot its off of….:diablo:

Thanks in advance!

TT

P.S.
Its not going on ebay really, its so hugely valuable I’ll put it in my pension fund, which isnt…:eek:
