18" milk truck wheels

I'm looking for some old ford "milk truck" wheels.They came on 40s,50s and some 60s ford 1/2 ton milk trucks,bread and mail trucks too.
They measure 18" x 3 5/8".
5 x 5.5 bolt pattern.
Any leads or info greatly appreciated.I also have lots of parts kicking around to trade for some also.
I'll try to attach a pic or I can email a pic if need be.
TIA......Shiny

These wheels were also known as ambulance wheels,some people call them divco wheels,but they didn't come on divcos.....Shiny
