Is the 1957 model 11 inch lathe compound the same as that used on the 10 inch lathes? Also, were some compounds made with the front lip screwed down with 4 or 5 allen head cap screws, or is this a common repair for a broken one? I'm looking at one and it has that "feature", but I've seen pictures of others that appear to have the same thing. I haven't seen it in person so not sure if its had the lip broken off and been repaired. Thanks for any input! Al
