PZ93C, confirmed that 4-screw M28 no-dash's sn is S221184, and it's still in the shop.
Also, today I brought home a couple of new (to me) N-frames, one of which fits into this thread; another M28 no-dash, 6", sn 190000 (previously I reported it as 1200000...wrong again). Anyway, here's some photos of it wearing some of those new Altamont's (...better than the goodyears that it came with, but still not quite right); also the newbe along with my 4" M28-2 (sn S2244xx):




Still too cold to shoot today, so I'll just have to make the rounds to some of the local gun shows to find some better grips. -S2
