I'm not going to stop someone from doing what they enjoy or making something "pretty" in their eyes (I mean look at us, we are an odd bunch for sure) but in the case of SP-ing things, at least get parts and build it in a manner that actually compliment the original design. Like the dispatch board, dont take a new galvanized housing and jamb it on and call it a day....not hard to find something period correct that might actually look kinda nice there.
If your going to botch something, botch it well (oxymoronic i know...)....ok, off the soap box
