I bought a Smith Pond Junction kit a while back that is just to small for my RR. It is their Prairie Station Kit, scaled at 1/24 it measures 12"x7"x6-1/4".
To say this is a kit is stretching that label a little. What it consists of is a pile of strip wood, some instructions and templates. I have no use for it, before I break it down for stock is anyone interested in it? I will give it up for $20 plus shipping, paypal only. SPJR is out of business, so if anyone wants one now is your chance. Speak up if you are interested, this sale ends on 7/21/2018.
