Re: 1957-1961 Fake Stack Questions

Will check out those images you mentioned.
I am aware of the 1954 stack on 476, cause that was in the films my dad shot in 1954. In this film there are no diamond stacks on 1957, but Earl was thinking perhaps there were.
No, 473 was the yard goat in the early 60's after 464 was retired, and the diesel was used as well, but it doesn't show up (#50).
If we knew that 464 was retired in mid-1957, then I would say this is 1957, just before its retirement. If in fact it was retired in the first 4 months of 1957, then I think we may be looking at 1956! The owners say it is 1957!
Thanks for the help.
