I note that it was mounted at one time, look at the screw holes and expansion and torque.

Maybe it is the real deal?
Thanks Joe, learn something new every day !Vega aircraft built B-17s, they were a subsidiary of Lockheed, basically located at the same facility. The YB-40 mod was done at the Lockheed-Vega facility in Burbank CA
ah !A/C Serial Number 6030 / Registration Number 42-5734. So 42-5734 is army number. 6030 serial production number.
Thise numbers are linked but historians mostly use the army number, so thats why we are used to that
Numbers you looked up are in the master records and they use the army numbers.

Rarely have I encountered the data plates riveted on, most are usually use small"P-K" screws. This not to say never as I have seen a number ofAre they not riveted on?
I've been in aviation for 40 years, worked on everything from Cessna 150s to DC-10s and many military aircraft, Every aircraft I've seen (that I can remember) had their data plates riveted. BTW, I'm an IA - if I came across an aircraft with a data plate held on with PK screws (unless they were one way screws) I'd have the owner correct it or I wouldn't sign off the inspection.Rarely have I encountered the data plates riveted on, most are usually use small"P-K" screws.

them riveted but more often than not, screwed on. Part, part modification, and component pates are almost always riveted in place. Just
my experiences.
The V140 was the model number (I believe for the YB-40) "V" for VegaMaybe I'm seeing things, but the stamping for the Model type appears to be V140, not YB40, and the plate seems to be in remarkably "new" condition, for something that's supposedly over 70 years old.
If it's V140, then could this be off a Lockheed V or VC140 JetStar ?
Saw that earlier.Found it at : YB-40 / B-17 Experimental Bomber Escort Original Data Plate 42-5734 RARE | #526990465
Seems like it was offered for sale on Worthpoint.
Spent almost fifty years now around aircraft. Began twisting wrenches in '75 and like yourself I've worked on C-150's, Pipers etc. Biggest thing I worked on was 737. But I digress.. Most of the military a/c plates I have were screw mounted from L-bird's SNJ/T-6's , C-54, C-47,Corsair FG-1D(beautiful yellow and blue Goodyear plate) right up thur the AH-1G's Cobras. I don't wish to argue, it's just what I've seen. It is nice to speak to you seems we have had a similar life experience as well as our love of aviation. Never got around to the IA stage, ex-wife was one, so I had my own personal one.

I've seen pop rivets as well

Try Baugher's site, go to serial numbers and on the aac/aaf side put in YB-40, it'll take you there. He lists both mil #'s and manuf#.Seems like the original Lockheed Vega project V-139 was the XB-40. And Project V-140 was twenty YB-40s. I can find the USAAF serial numbers, but not the Lockheed Vega serial numbers.
