most are mine are in decent shape- a few need electrical wiring for sure and so far the one treadle machine(new home) is the worst condition- just afraid the others will get like that and I dont' understand how it got that way - the others that have been out of cases are dusty but otherwise not damaged.
so..sitting unused inside the house will only cause them to need some dusting/oiling? if so I may just do a little mini-thinning of ones people are wanting and I have extras of and focus on new stuff I like and not deal with keeping parts, etc. I really need to go through them all - just haven't had time- and see what all is there. pretty sure there are a 3 or so stylists/touchnsews or whatever and I know I gave up on one of those the one time I attempted to sew with it -t he stithces were awful and Id idn't have time to fiddle around with it and went to the next machine.
