In my opinion, you did not overpay for a low three-digit specimen. That's a very nice rifle, even if altered. Now, you didn't get a steal, either, as that is pretty much full current high-retail, and you were wise to hammer the seller as $2499 would have been too much!

Will be interested to see if the stock has a rod channel filler (I'm betting it will) but the flat butt with no trap will only be found on unaltered stocks. The late 1892s (like my 20196, which was never altered) had the curved plate from new, but no trap. This "intermediate" butt-plate style (also used on the fabled Cadet rifles) is not often seen.
