Stan I will keep an eye out for your 32 inch hammer gun Lagopus on here would probably be a good contact for sourcing such a gun. The UK guntrader site has a good turnover of British guns and might be worth a look also.
Thanks, Konor. There was lots of discussion about it on a WTB thread I posted some months ago. Conclusion by Toby Barclay was that guns like I want do exist, but are very rarely seen for sale, and that my chances of finding one are super slim unless I get very lucky. Several have sent me links to guns that were almost right, but had one issue or another that knocked them out of the running. Most often it is lack of choke. My best bet is on your side of the "pond", I think, but I have had English gunshops that wouldn't even reply to my emails about certain guns they listed. This one in particular.
