I have several Weaver brass engines including a Pennsylvania torpedo and a NKP Berkshire. They both seem large compared to some of my other scale engines. I also have a Weaver brass GG-1 that seems to be exactly the same size as my plastic Williams version. Since I can't easily measure the two steam engines against any published prototype dimensions, does anyone know if these models are 1:43 or 1:48 scale? Just curious!
Those early brass GG1's are true pieces of art! Yes, they are 1:48 scale as should be the Berkshire & Torpedo.
First run of the GG1's had motors without flywheels and sometimes required a deft touch on the throttle to bring them to a smoot stop as they would not coast. The 2nd run had flywheels which were a big improvement. If you have an old transformer, many of them started at 6v - 8v which would be a jump on startup as well as an abrupt cutoff when slowing down. Better to have a more modern transformer that started at 0v-2v for smoothness.
