Greetings
I have an original Enfield p53 rifle. It has an unusual marking on the lock; Birmingham small arms trade in a horizontal oval. I have never seen a lock so marked.

Crown at rear of hammer. Typical Birmingham Small Arms Trade marking on the stock. No other maker names except for this: On the right side of the rear sight appears to be T. & E. P.

Also, original ramrod seems to have british markings as well.

Any info?

Thanks
