Finding a Warming Rack for a Junior might be the ultimate "Pot 'o gold" find.
If I were you I would either grab a Stainless set from Rivers edge and have it cut down to the 18" width for the Junior or contact them to see if they could make you a custom set...
Sorry, I'm holding on to that drip tray for my personal grill as they are becoming harder and harder to find.
Your best bet is to keep what you're doing...trying to grab some parts grills that have the parts that you need.
Let me know as you're close to me here in Mass for pick up.
I know from shipping a cast iron skillet that it ain't cheap!
I know you were saying the frame on your Platinum is rough...might have half the frame to sell as well.
With the talk here of the older Weber E-310/320s I was going to put my recently acquired Weber #7532 Cast Iron Griddle up for sale on the Forum. It is brand new in the box and never used. It fits 2007- 2010 Genesis E and S series gas grills.
Any interest just let me know.
Cruising Facebook Marketplace and came across this rather unique Thermos grill-
Not only glass front but glass side shelves!
The knobs look like older Weber's too
Insides appear almost new, very little use. Appears to be a cast aluminum box and lid too.
