Okay guys....I have a question that I hope someone can answer. On the Pecos River Brass cars, what diameter truck mounting screw was used? These are a shouldered screw, with a short threaded end. I think these were very similiar, if not identical to the US Hobbies ones from the Max Gray era. I need to know if these are 2mm, 3mm, or some oddball size, like 2.4mm. Unfortunately, I do not have a metric rule, or a micrometer to check with. Plus, (Pecos) John Smith is long out of business. Thanks in advance.......
