Try posting your question in the McCulloch Chainsaw thread in the stickies section, you will get a lot more attention there.
To get started, the 1-52 is an 87cc front tank model, 1-53, Super 250, 300, 380, and 380A in the front tank models all match the displacement. The 1-53 is the only one (off the top of my head) that also has the 5/8" crankshaft and threaded clutch, all of the other are tapered and 9/16" at the clutch bearing.
