Post your tunnels you may have here, if you want to.
MARX PREWAR #390 FARM SCENE TUNNEL
This is the Prewar Marx #390 Farm Scene tunnel, it is a common item.
There is also a Marx #309 Camouflage tunnel this is the scarcest one to find, collectors often call this one the autumn leaves tunnel. I think because of the "camouflage" coloring it did not sell in great numbers.
Then there is a Marx #392 Mine Scene tunnel which is also quite common.
Most of these went for around $.98 cent when new.
All the tunnels come as two halves joined at the top by interlocking 'fingers' and at each end by either a metal clip (early versions) or a screw (later versions).
This is an earlier version.
I don't know the year, I am guessing middle to late 30's?
This was also saved from the trash/dump pile from my Bro in law.
