Parker Bros overload proved stamp
 
Sorry if this has been addressed in the past. When was (year) the oval stamp first used that has this wording:

Overload (adjusted from overloaded)
Parker bros
Proved

Thanks folks.

I’m pretty sure I have some guns with the stamp made before 1928…but all in the mid-1920s.

This one was completed Feb.27, 1927 and is the earliest I have with these stamps.

Is there any description known about how / if the barrels were supported when these stamps were applied? It would take some force to put them in place so that they appeared equally impressed.

Quite right, and with enough pressure to deform the chamber, so it makes sense that it was stamped prior to finish boring.

Then how would we explain the lack of chamber deformation resulting from Remington Arms stamping date codes when a gun was in for service or repairs...?

They could have use an arbor inside the the chamber for support.
