The Bauer was all stainless steel and investment cast parts. The latter was 'the way' to do things at that time in firearms mfg.
Good or bad depended on the quality of the castings being done for you. Hardly anyone had their own casting facility. Ruger was about the only one.
The Bauers weren't too bad as far as overall quality and the asking price at the time. They were quite popular because of that. The orig Browning Baby 25 that they were a copy of were always several times their price.
They had some rough internal parts that didn't need any machining or little fitting from the investment cast phase,,so they didn't get any.
The outside got belt grinder polished on the frame and slide flats and the preliminary bead blasted prep usually left in the rounded and undercut areas. Not an unattractive look, but done to save labor and time.
Some were polished all over.
Like any mouse gun they could be picky about ammo.
I remember engraving more than a couple of them in the 80's when they were popular.
The investment cast frame and slide would sometimes expose a small hidden flaws when chiseling along. But that's something any investment cast part can surprise you with.
Ruger #1 levers were well known for that.
I do recall a number (5 or 6) of used ones for sale in a shop I worked in in the early 90's. They were in kind of a pile, in a display case at the very end of a bottom shelf.
They were all marked '$49.95 each. No returns/no guarantees/may be parts missing or damaged.'
I didn't bite.
Collectors gun?,,I don't think so,,but then I'm not a collector.
Some people collect matches,,so what do I know.
Asking price just seems a bit high to me.
