I’m from Philly, PA and lookin 4 old PCC cars, trolleys
What scale are you looking for? Ebay usually has a bunch on its site. I have an O scale TTC PCC street car but its just a ornament.
Corgi makes very nice die cast non-operating PCC cars in 1/50 scale. There are motorizing kits avalable for them in both O gauge (3-rail) and O scale (2-rail).
Trollyville has a lot of information on HO scale

Bowser makes a PCC car, undecorated, in both powered and unpowered. These are HO. I’ve got one, but painting is on the back burner so it still looks pretty much like the out-of-the-box pic. You might find a decorated one on eBay.
