Inherited firearm with scrubbed S/N
As the title states I just inherited a firearm with a scrubbed serial from a deceased relative. The gun is a pre-war 1911 possibly 1917/18 based on my limited knowledge. Is there anyway I can recover the S/N? I can only make out the letter N.
Also has anyone else been in this situation? What are some issues I may face? It's a neat piece of history and I would like to try and find more info on it.
