I bought a Platinum Cup 1911 .22 conversion about 20 years ago. Had to send the obligatory money order and printed order form.
What showed up was a beautifully machined aluminum slide with adjustable sights, satin finish, crisp edges, and zero tool marks. With it was a satin finished steel barrel and RSA - also impeccably machined, plus a magazine carved from a billet of aluminum that functioned(s) flawlessly. Having done my share of machine work I know what quality looks like. All this was packed in a nifty, blue plastic case with molded recesses for each part.
I mounted it on an aluminum frame I machined myself and ended up with a beautiful, lightweight, fully reliable .22LR 1911.
Was a time Ciener was the only game in town. Whatever might have been his shortcomings, selling anything less than top-quality conversions was not among them.
