OK, well, here's my list:
Non-Electrics
1890 Davis HAVF1 - head that needs a base.
1915 David NVF in a treadle - plan on using this one
1950'something Singer 15 in a treadle - does get used
Decorah Posten treadle irons only - plan to use for the 1890 Davis head
White treadle cabinet only - bought some irons, but don't know if they fit yet.
1909 Singer 66-1 Lotus decals - needs a treadle base - DH working on designing a multi-use base for all these
1915 A. G. Mason "New Glenwood" treadle head - a prospect for that MU base
1924 Singer 99 - converted to a hand crank - love this little one!
OK, now the electrics:
1917 Western Electric portable - motor just rewired by our friend Joe
1948(?) Singer 128 portable
1953 Singer 301a - my daily piecer and usual travel partner
1956 Singer 221 Featherweight - my traveler sometimes
1957 Adler in cabinet - Has some tension issues, so haven't worked on it in a while
And a lovely Singer cabinet with curved drawers that should have a 201 in it but doesn't.
1 Singer 15 that I haven't even looked at yet because it's frozen up
1 15 clone that needs a new tension take up spring.
I think that's it...so, 12.
