The 1935 catalog now shows only a single tunnel image and now only lists 3 tunnels
O gauge listings include:
261 - 8.5 inch tunnel
247 - 11 inch tunnel
I was able to identify the 247 tunnel simply due to acquiring one with a price tag on the inside that listed the number.
Note that this tunnel does not have a building moulded into the side.
Both of the above tunnels being listed as Non-lighted tunnels.
A single lighted tunnel is listed as
246 - 15.5 inches and it is noted that it works with either standard gauge or O gauge.
First, I would note that although it is listed for either standard or O gauge, this tunnel does not have the clearance for some of the earlier Wide Gauge locomotives with pantographs on the top.
Again, it looks better lighted
