Thames Arms company most likely? Seems they produced copies of Hopkins and Allen and also H&R top breaks. Couldn't find much more info on them. Hope the info helps though.
Thanks. I've been working on this for friends of mine. Found the gun in a box and didn't know what to do with it. Not in this state so I told them it might make a good paperweight. Going back down this weekend. I'll get another pix. It's a .32 five shot break top.
