Sources for 15/18 mm 1930s USA Street Details?

[FifteensAway]

While this will be for a Pulp era Gangster gaming setup, I'm posting here because I believe the Workbench folk are more likely to know which way to turn.  Or so I hope.

I'm looking for things like trash cans, phone booths, police call boxes, fire hydrants, man hole covers, vendor tables, etc., for circa 1930s era street details to bring some 'extra life' to my games. 

So, who can direct me to items that I can buy?  I'm not quite ready to turn to scratch building and I don't have a 3D printer so that is not an option (though buying from an affordable and reliable 3D source might be).  Ready made resin is okay and metal is definitely okay.

Appreciate any help anyone can provide.

Thanks!

HO (1/87) model railroad suppliers will have everything that you could ever need. They'll work fine with 15/18mm figures.
