Destry-
Thanks. I have three on my UK Shotgun Certificate. Two have been processed and have the necessary paperwork to get back in the US. I believe these are on a form 6. I spoke two the importer who processed the two and they told me no problem to import if it older than 1898. No forms required. I will go by H&H and see if I can get a letter stating the date it was made. I will also copy the blue book serialization pages. I printed out a Holt's estimate for similar gun coming up for auction. I will also have a bill of sale.
Thanks again.
