So here are a few early miscellaneous items
A boxed 82 Tunnel. This is not mine and I thought I had a picture of the tunnel itself, but could not find it. So here is a picture of the box. Finding boxed O gauge tunnels is rare, but I have seen a few.
This next tunnel measures 9.5 inches long. I suspect it would be a #81 tunnel, as the tunnel portals seem to bow outward on each end. Side A

A 12.5 inch tunnel. Can't really say what number this would be, but suspect somewhere between 82 and 83. Side A
Side B
Next up is a 14 inch long tunnel. Suspect this is an 83 tunnel. Side A
