my sister found this featherweight in a garage sale. paid $125 for it. has original case and attachments plus the manual. it seems to be in excellent condition. and she gave it to me. i think i did good, right?
it also came with a paperback book called featherweight 221 the perfect portable. according to that, my serial number is from 1950. it has a new 1/4 inch foot on it and has the lubricants too. i guess it was being used up until recently.
so is it better to use it on a regular basis or keep it in mint condition for value?
The answer to that may depend on why you want it. If it were mine, I would use it! But if you want it only as an investment, then maybe only use it once. However, I don't know much about featherweights so I may be all wrong.
