The 3D Prints are out!
The prototype (grey) is fitted for 8 inch wheels. The carbon fiber print (black) is fitted for 6 inch wheels. Since I don't know which size wheel came with it originally I'm going to try out both. If the prototype fits and looks better I'll paint it and use that.
I was able to source a set of 8 inch wheels and 6 inch wheels on FB Marketplace for $5 for all four. Best part is they were literally a block away. The guy also has an old Master Touch he's willing to part with for $30 but it's in bad shape. It looks like it's been dragged. So, I'm just taking the wheels for now.

Tried the 8 inch wheels, also tried a 3/8 inch rod and some rod clamps I got on Amazon to try to mount them. With the Prototype Leg it's got good cooking height, but it looks kinda goofy. Also didn't like the rod going all the way through, it made it look like a coat hanger.
The 6 inch wheels weren't too bad, but one of them was a little chewed up. I had ordered a set of non-Weber wheels on Amazon but they were so embarassingly badly made I sent them back without posting an update.
I found some 3/8 inch axle bolts I had for repairing my wife's Honda Lawnmower and decided to see how they worked... And BOY did they work. I really like how it looks.
Also cake:
My order from McMaster-Carr arrived and it had this little Olive Knob:
I fixed the rivet on the hood so now it doesn't just fall off anymore but it can still be removed for cleaning, and I manage to preserve the original rivet.
Here's the original grill. It has an enamel coating on it, but it's got some marring and chips. Don't think I've ever seen one like it before.
Got the hood put back on and the ash pan with a new charcoal grill I picked up at Ace. It's for an 18" Weber Original Kettle, but it fits this beautifully.
And with both grills inserted:
And that's it. It's "Done!"
I think I'm going to order some fresh new wheels, either Weber or a high quality generic. If anyone has any recommendations, I'm all ears. I guess I was closer to done than I thought. Once the prints came off it was pretty quick to get everything in order.
