I really like the practical, rough and ready aspect of that brass aperture sight,....and reckon that once I had it all dialed in I'd soft solder the whole works solid.The stem looks a bit fragile, for beating around in the rocks and trees.
When you fellas are blessed with an original vintage piece, but saddened by the fact that the original "kit" is long gone,....either lost or sold separately, ...give me a holler, and discuss FINE quality recreations therefor.
Sights,false muzzles,lock parts, ..."whatever"
You are going to LOVE that Merit disc, RWE
