I picked up an Alpha big end assembly for a V twin or a flat twin with side by side rods, it is an Alpha type one (tapered with shoulders to retain the bearings) I have an Alpha book from 1970, but it dosen't appear in it so it could be older, maybe 1930's (or newer) than 1970. I have listed the dimensions in inches measured with a cheap vernier, so they may be out by a couple of thou. Any help greatly appreciated
