Not showing up, for me, in a search od W&S .410.
Please post an item number if you would. Thanks.
I suspect he is refering to this one: 101720578
It is an Army&Navy and states they were made mostly by Webley&Scott.
There are 9 English 410'as that show up and none are listed at over 28". There are two cheaper O/U's with someone in Texas, but they don't list the barrel length. With two H&H and Woodward guns, you can't spend a lot of time advertising for the minimum profit you mike realize. The ask is only $98K and $225K.
