This nice little tunnel features beautiful rolling countryside graphics and was made starting in 1949 according to the book
"British Toy Trains
Featuring all those other British toy train manufacturers
Book 4 of 5 - Wells-Brimtoy Ltd 1946-1991
One Hit Wonders"
by Michael D . Foster
I can't seem to find how long it was in production but apparently Brimtoy shut down production in 1983 so it wouldn't have gone any further than that. The tunnel disassembles into two pieces but when these photos were taken, I just didn't do that to show the process - sorry. The lithography on both halves is exactly the same so a full photo workup wasn't necessary but now I wish I would have tried to take a few more. Enjoy! Opa Fritz
