4 Wheels & 2 Axles welded together 7 1/2" or 7 1/4" gauge

Description

These are a whole new type of wheels,
they
are not solid
,
they are made from 11 gauge steel formed in a hydraulic press
,
the tread diameter is 4.5 and have 1/2" axles welded to them
, the shape of the wheel conforms close to IBLS standards. Are they strong!! yes I have had over three hundred pounds on them and the wheels didn't even bend at all, well maybe .005 thousands.
ONE SET IS 4 WHEELS AND TWO AXLES WELLED TOGETHER
enough for one truck.

You might be interested to hear that the axle sets that you sent me in 2011 are still in use every day on our short backyard line. Even if there are no children playing with our tram (streetcar) we still send it around the track once a day to crush the grass, flowers or weeds that would otherwise grow and cause the wheels to slip during wet weather.
