Here's some background on track.I have some HO track but what is the different code #'s for? How do I tell what my track is? Thanks for any help.
Yes, that is correct... A prototype is something in real life that is used as a model to create a scale sized piece, so anything that is "proto" is accurate to real life...In the article it uses the word "prototypical". I have seen 'proto' here and there in my research. I'm am guessing it refers to 'exactness' in detail & size. Correct?
