I collect, restore, and use vintage and antique sewing machines 🙂 No plastic gears in my house! lol
Use a baby wipe to clean the outside. It won’t bother the decals. Just don’t use water. It’ll cause the decals to silver.
If there is an oil build up that dust is clinging to, use GOOP (you’ll find in the auto section of WalMart). Smear GOOP on, let it sit for a few hours, and wipe off with a dry, soft cloth. Repeat until satisfied (I am currently using this technique on my 1883 New Home).
As for the gears, lots and lots and lots and lots of sewing machine oil. Soak it ALL down. Inside and out. I buy mine by the gallon when I can.
Remove the back plate, side plate, and needle plate and polish with metal polish.
You’re missing a few parts from what I can see here. The belt guard & bobbin winder are the first 2 that come to mind. You’ll also need a leather belt in order to treadle if you so wish. You can find all those on eBay or buy a junk Red Eye 66 on Craigslist to use for parts.
I’m sorry your cabinet is sad. Is it just the veneer or worse? I use oil based rustolium on the irons and gear grease on everything that moves.
Whatever you do, DO NOT USE WD40 ON ANY OF IT. You will cause your machine to freeze. And it’s bad on decals.
