I'm going to go out on a limb here, and this is strictly speculation, but after I looked at the gun at Hill R&G (actually examined it in hand this past spring), I'd say these guns have a very good chance of coming out of Chas. Osborne shop. Osborne made actions and guns for the trade, these two guns look very similar to other guns I've seen from Osbornes. I still wouldn't doubt that they originated from Midlamd, BSA or even another trade maker like H, B & P. All I'm providing is speculation, sorry I can't help more.
When I said the quality wasn't there, I didn't mean to say that guns quality was poor. It's a good quality gun, obviously. In my opinion, it's just not up to the standard of the higher end of the trade makers.
