I've bought a goodly number from Taylor's ( used to buy in numbers for films )
The last few Remington s I got was for "Into the West" all were quite nice... but I've also dealt with them for my use as well...
The only Remington I have now is from them, it's the Factory Conversion and has been a very good piece.
Cimarron & Buffalo Arms are two more sources , I have worked with Harvey s Cimarron , but have not purchased from Buffalo Arms
( just never have ) I'd might contact Taylor's, as my first attempt....
