Beautiful example of the SRT 101, Rick. The SRT series are among my favorites as well. Minolta slightly modified the SRT 101 over the years. Early ones had the single slot take up spool (still IMHO easy to load) but later went to multislot later. The highly desirable mirror lock up eventually disappeared during the last few years. I have several Minolta wide angle lenses, but never owned the one in your picture.
