Does anyone have any links to aid in the valuation of a Darne V1 in 12 gauge - its approximately 50 years old, I have the option to purchase said shotgun but the only google search I can find is a Holts Auction that finished up @ Ł180 but the details are limited to Darne 12 gauge so not really enough information.

I want to be fair to the person selling it (they are not a shooter) but don’t want to overprice it either, as a side note I am looking at it for myself and it will be used so I am not trying to buy it to move on I just find it a really interesting piece.

Thanks in advance for any help.
