The Remington R-B is one of my favorite single-shot actions. I regret not more vigorously collecting them when they were plentiful and more affordable.

I regret selling off several that I once owned: 1914 model in 8mm Lebel with bayonet, model 1867 U.S.N. carbine in .50 Carbine, and Springfield made model 1871 in .50-70.

I hesitated on some specimens I should have bought!

IMHO - Rolling-Blocks were a 'Sleeper' in the collecting field for a long time. They were plentiful, undervalued, and under researched.

Too late smart! - I never heeded my own advice "to collect them".
