Awesome thanks @toolhead for the info
Brother toolhead speaks the truth but I feel a little perspective may be in order regarding the hard-to-find original parts for the SS Performers.
charcoal bucket, metal lighter instruction plate...tank assembly bracketI don't know that these really "go bad" often. The SS used a 5lb tank, which is expensive ($50-ish if you need to get one) compared to how much gas it can hold. So if you'd wind up using a 10 or 20b tank and another hose ... its bracket isn't an issue anyway.
I'm using the tank my '92 came to me with, an '01 I think ... when refilling, my local ACE hardware doesn't seem to care it's expired although I have to tell the counter gal it's a "4lb tank" because a "BBQ tank" gets priced as a 20lb tank. I did also change out the old connector for the modern "acme nut" style.
old style ash bucket and ash ring, ash catcher bar, 7409 ash sweepThere's a lot of info about these parts on this site. I bought a reproduction (aluminum) bar for the 7409-style sweeps form zavod44 but after about a year or so traded the entire assembly for the newest style ash can and "H" ash sweeps. In my opinion the "H" sweeps are superior because it just fits together; there's no attachment/adjustment bolt. The current or last-gen ashcan ring can attach to the oldest One Touch models with either radiator hose clamps or screws into the leg sockets, and (again, IMO) supports the ashcan more securely than the old setup ever could.
Point being, new parts can be adapted to work, and work better, so don't fret the common parts not being available for SS. The frame on the other hand might need some work if rusty. There's info here about that as well, bicycle frame star nuts or some such I think.
Edit: The hose that goes from the regular to burner tube is expensive now from Weber, available only as a complete assembly with other parts not usually needed. That said, its another part that doesn't usually need replacing. The regulator, of course more commonly needing replacement, can be swapped out with a Mr Heater from Amazon for less than $15 for example.
So pick what you want, we can get 'er going! If you're tall, consider the newer styles (not SS) because those machines are a little higher. Not sure if that was mentioned.
