Anyone familiar with this stamping?

Looks like a WWI P-14 a 303 version of the Model 1917 rifle.

ERA stands for Eddystone Remington Armory.

That is of great help.

The number 2 indicates 2nd variation barrel.
The star that is underneath indicates this is a Mk1*..enlarged bolt lugs and recesses in barrel.

I believe all of that makes sense. It has been rebarreled to a 300 H&H and put into a gorgeous maple stock.
