It's a bit silly, but I grow roses, read about roses, root cuttings of roses; and I have found a few old Singers with roses! I want one lol. I think they are VS2, maybe model 28 has them, possibly model 12 too. I could easily start a decals collection, though I would be forced to document it in photography.
I find some of the Touch & Sew models interesting too, and I think some in the 500 and 600 numbers have all metal internals. That's always a pluss, but I'm not very strict about it. I can't say I have any plans for a serious collection, and I find other brans interesting too. There are some very nice early zigzagger, the best ones are (arguably) not Singer.
It's interesting to compare developments, like the 99, it came about as a popular demand for a 3/4 size version of the 66, over the years it came in various versions, it was given a stitch length lever with backtak, a few alterations to the race and hook (I think) and the last one, 185 had an updated exterior too. They came in various casings, at least two suit case types, dome lid case, and the last one in a plastic as well as a wooden case.
Exterior can be traced too; like the 201K23, the aluminium version of the 201, a matching new look was given to other models too: model 15, 185, and even 319, probably others too.
You could trace rotary bobbin models; 101, 115, 201.
A collection is sort of guided in what you find interesting. I'm sure there are lots of literature on this, and much better sources than the web.
