Please do send me the details.Would like to know.
Thanks for the links.The Trap SXS guns you speak of are most probably live pigeon shooting guns,the earlier version of the present day Trap shooting.Many continental gun makers still produce live pigeon guns.The H&H boxlock looks to be a Birmingham trade gun built for H&H.I could be wrong. I am aware of Holloway and Naughton,though I have not seen this particular offering.
Yes, we all are entitled to our opinions.Free speech and all.I am not an expert.Trying to learn. We can pick up the discussion on the London gun makers on a different time.This was about the sidelock Vs Boxlock. Thanks for sharing your inputs anyway.

Best-
