I don't exactly know how "vintage" this is compared to the age of my HO collection in general, but I picked up this set of Burlington FTs from a co-worker who was giving away his dad's trains. These are Overlands produced by Ajin so I am guessing 1980's?
Overland's FT's came out in 1999, so they're still from the previous century.
And they look a heck of a lot better than Tenshodo's.
