I just got a 301, couldn't find a featherweight for a reasonable price and picked up the 301 for $15.00
SO I HAD TO GET IT! I'm not to familiar with the 301's cant even find the number plate. but it's 1:30 AM here, I'm not looking too hard LOL I ran across a manual while looking for info, thought maybe someone else might find it useful
