I am helping a friend try to ID a micro crash site on a gunnery range in FL. So far the only diagnostic part has stumped me. There is a chance it could be a missile or drone.

The part number is 205191-3R. Part numbers being ink stamped usually means later than WWII, but not necessarily. The font does look old, so that could be WWII era. (Yea, I know that does not really help!) The dark brown on brushed on top of the zinc chromate appears to be an adhesive. This to me would suggest jet era.

Bell used ink stamps Bell 206 maybe? Font looks older than that.

Douglas (mostly post WWII I think) used ink stamps. 206 is a part number used by SBDs, but no matches in my SBD parts manual.

Vought used ink stamps and A-7s have part numbers in the low 200s, but not as low as 206 according to my notes—but I do not have an A-7 parts manual.

I think Grumman and Northrop used ink stamps, they even had a continuous part number (without a dash or letter in the first couple digits), but nothing that would fit 205191-3 in my prefix notes. 

One of the projects thank I would like to do, but never seem to have time is to make a note of what companies/planes used ink stamping of parts numbers, and also add pictures of actual part numbers to my part number prefix list so it is possible to compare fonts.

Thanks to Dan D.

205191-3R is an angle in the wing fuel tank assembly that is applicable to the following aircraft:

F-94A, T-33A, F-94B and T2V-1.


I would be interested in hearing from others if they have photos of other ink stamped part numbers from other crash sites where the plane type is known.

After a quick look I found just two so far.

North American F-100F part is inked (F-100F s/n 56-3790 crashed 25 Nov 1958).   1st pic.

Republic F-84F has imprinted p/n but an ink stamp (F-84F s/n 52-6873 crashed 3 Nov 1959).  2nd pic.

McDonnel Douglas DC-9 used stamped part numbers as well as the Douglas DC-7. This photo is from the wreckage of the AirWest DC-9 in the San Gabriel Mtns. north of Los Angeles.

Bell Helicopters did use ink stamps on their airframe and components and a "204" or "205" designation would be from a Bell Huey Series Helicopter, but the number is usually spaced with a dash. Can't seem to find a Bell Helicopter part with your particular number though. Look around for more parts.

Inked numbers...  I hate em!!...  Douglas?  You hear me?!

Sorry, inked part numbers are a pet peeve of mine in wreckchasing.  

Many vendors use inked numbers, particularly 70s and later jets.

Seems darn near everything on A-4s was inked.

A lot of stuff on Martin B-57s was inked.

It's frustrating to get to a site with aluminum everywhere and not a single part number in the mix because they were inked and have weathered away.

Agree on the T-33 family ID.  The 205191 number is in the T-33 IPB.  The fragment has brushed on sealant and bits of black rubber which would make sense on a wing fuel bladder related part.
