With a relative small sample size, what we are seeing may be more a function of which ones collectors keep/buy for the safe, vs. send on down the road; might not be representative of actual produced ratio.
True. The thing that surprise me is I seem to run across takedowns 3 or 4 times as often as I run across the solid frames. Finding a pre-1910 1899H seems pretty darned hard, and they were only solid frames. Didn't seem to sell a lot until they added the takedown feature to them - at least that's what I thought.
