Parker Bros overload proved stamp

[Brian H]

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...?

I hope that was a rhetorical question. The amount of pressure necessary to impress the tiny font of the Rem repair code stamps is only a minuscule fraction of the pressure necessary to impress the proof stamp.

Take a pencil eraser and push it against your finger tip. Now take a common pin and apply the same pressure. If that doesn't help explain it, try the above test on your.....oh, never mind

1. No Edgar, it wasn’t a rhetorical question at all.

2. But you will notice that the Remington date codes were stamped to a greater depth, for the most part, than the Overload Proved stamps so what does this say to you Edgar?

3. I couldn’t find a pencil Edgar… (please refrain from a witty reply… it’s too late to match wits with you.)

So they stamped it “Overload Proved” before they tested it?
