For Sparkbrook looking for his Grandfather's rifle:
There might be hope. Some years ago while I was set up at a gunshow, an English friend showed up with his father who had just immigrated from England. He wanted to know if it would be possible for him to buy a rifle as he was used to the regs in England. We convinced him could with proper ID and a NICS check. He wanted to get the kind of rifle he carried in WW II. He went off looking and in about 30 minutes he returned carrying a No. 4. He said while it was not the best looking one he found, it somehow "spoke" to him. At the next show, he comes to my table and informed me that after he got home he pulled his records from the war and discovered the rifle he had acquired WAS the rifle he was issued during the war. He even was able to describe how a number of nicks and bumps got onto the rifle from his using it.
So miracles do happen, don't give up.
