Ah, yes. You must be Denis Prisbrey; The Survivalist Papers Volume 2016-1: Lipsey's Ruger Bug-Out Bag Bearcats.
I notice Lipsey's Bearcats sell in the $600-700 range - a bit high for us common knuckle-draggers. But for the likes of us there are solid, used BC's in the $300-400 price range. I think my 1959 model cost me $330 just last year - a steal.
Does your treatise discuss regulating fixed sights? Hey, I do have a Kindle and for $3 I guess I can find out.
Thanks for your input.
Peace,
Bud
