Does anyone here own either of these locos and, if so, would you be kind enough to measure the diameter of the wheels for me? No calipers needed, just a ruler and mm or inches is fine.
I ask because I'm planning to bash or scratch a Dunkirk Class B and info on the prototype is hard to find. Making a guesstimate, I think the wheels are roughly the same as the Bachmann On30 Shay and Climax.
