lol...I love your "um"....my machine looks like the 301 but its the color of the 401, has cams, and has a lift up extension to the left like the 301. Can you tell me what it is?
haven't the foggiest - the 301 does not take cams
the 401 does not have an extension
AFAIK the 301s and 221 are the only ones with extensions - so who knows
why don't you post a picture of it so we can figure it out?
