That is a quote worth keeping.

Firstly welcome to NitroExpress.com. I hope your scratch your itch and also have fun here.

The first thing I would do is find the name of a good gunsmith (or two) in the UK who is very experienced with repairing or building double rifles and will do a thorough check over of any you seriously intend to buy. After doing an elementary check over yourself it is very much a good idea to have a professional do it as well with a written report.

".300 Sherwood"

This would be quite a marginal round, wouldn't it.

"Sidelocks"

Obviously this will add to the eventual price.

".400/.350"

I think "4seventy" on these forums has one of these (?) but his I think is a modern creation on a shotgun action (?) . He is a hunting guide and has been absent for a while, as he is probably in the bush. He uses it for wild pigs and also as a backup on scrub bulls in Far North Queensland.
