Lancaster Six-55.
Hello Superman 36. That saw looks very much like my Lancaster Six-55. Is she a runner? I haven't been able to get much information on the saw as yet. There is part of a sticker or decal on mine, the only numbers I can make out is 55-1 on it. Otherwise I see no model/serial number on my saw. From what I can tell it looks like she has an AH-47 engine and that's about all I can tell you about the saw other that it appears to have a single diaphragm carb on it. I was thinking a Tillotson H or HC carb, but they look somewhat different. Mine runs fairly well, so haven't removed the carb to check it out as yet. The sprocket bar and chain have seen better days, but I believe are original to the saw. OK, you take care. Lewis Brander..
