After digging around thru some of my "stuff" I found a few of the catalogs that you guys said might be helpful in finding replacement bearings for my ALF 12. I didn't find the info that I was looking for, (You bought replacement parts thru ALF directly) but there was some cool info in these books. Before I put them away, I can/will post some pics of dimensions that the HAMB guys may be looking for. I have 1928,1934,1939, and 1949 books
