When the 52xx locos were converted from 2-8-0Ts to 2-8-2Ts, they would have probably retained these wheels.
Later 2-8-2Ts, 72xx had wheels with larger hubs.

A full set consists of 2 x P75 leading, 8 x P229 driving wheels and 2 x P149 trailing wheels.

Suitable for Gauge One Fine or Standard

The prototype driving wheel weights are surface mounted plates and are not cast in.
