There seems to be a lot written about the earlier Singer machines (ie: the Featherweights, etc), but I have not been able to find much on those fabulous, all-metal, gear driven machines Singer made in the
50's & 60's. I've often heard that machines such as the 301 and 401 were some of the best Singer ever made (I love my 401!), but I can't find much info on any of the other machines in those series (for example, the 328 or the 421).ISMACS only has a little info on the 301, 401/403/404/411/431and
500/503 models from this period. And, many sites that offer old manuals say, for example, to use the 401 manual for the 403/404/421/431 machines.Likewise, can someone suggest a source for a list of the accessories (including part numbers) that fit these older machines?
Thanks! Malcolm
P.S. Re. the 401, ISMACS also states, "Some early models had holes cut in the bed for use as a treadle machine." Has anyone ever seen one of these?
