Walthers Blue Star ready mix

[Canadian Atlantic Railway]

I bought the Walthers Blue Star Ready Mix plant to use on my modern day short line and since I am backdating to the 75-85 era (probably 80+) I was wondering if the structure too modern for that time period? <!-- m --><a class="postlink" href="http://www.walthers.com/exec/productinfo/933-3086">http://www.walthers.com/exec/productinfo/933-3086</a><!-- m --> It would be a key structure and I would hate to have it look out of place.
