Drawing number

Can you read a drawing number on the barrel?

The bottom one has a larger barrel support bearing surface dia. than normal ,that is odd i can think of two reasons 1) slowing the gun down on purpose or 2) to fit worn out supports that could not be replaced at the time Any one else case to conjecture ?:help:

Any markings on the barrel that might date it ?

yes there is a drawing number but Im at work now and bored, so I cant get to it right now. Will post drawing number tomorrow. bought 10 of the $55 special at OOW and really happy with them, some outside surface rust on some of them but 7 gage TE at 0, 1 gages at 1/2, 1 gages at 3, one gages at 8 . what a super deal !!

Ok just got home, looks like all the other barrel have D-28253 A17 or A10 or A8 this one has only D-28253-A must be a early barrel, it also has FAM on it and a serial number

Looks like it just got passed by on the final machining step somehow.
