Thank you for the input and information Gentleman. That helps a lot knowing some of your observations, these takedowns have become a favorite of mine. I haven’t seen one past a 1910 either so that’s an interesting question. But like you say, if the option could be custom ordered then it might show up at random, and it would be neat to see an example proofed at a late date. I was looking over a friend’s spare parts the other day and I noticed one takedown trigger guard with an engraved serial on it just forward of the screw hole and perpendicular to it, I presume this is probably another English one, I wonder if that numbering style is characteristic of anyone? I’ll take some pictures of the sights on my project when I get home l.
