I'll look to see if I have a Catalog close to your year, I know I sold a 1955 catalog a few months ago. I have several correct crank handles also, if you need one, so you can crank those booms down some. I had an extra set of 525 hand rails but sold them back last spring. They are unique to the 525 models. If you don't find any, the round W35, W45, 490, & 515 rails will interchange.
