Either I'm misfiguring or Catt did, but at approx. 5/8" tall and over a half inch wide at the base I think #1 gauge (which like G isn't a scale) is probably gonna be close.
Yeah Ty , I am selling for a guy on Ebay and he doesn't know what size equipment it is for either. I have searched the web up and down for it and can't find any.
I have an email to a live steam group and am waiting . From what I can read it may be for 3 1/2 " scale. The pieces are 5' long and bolt together.
Thanks , Mike
