Going through my stuff, I found a packet of Robert Sloan RGS Goose brass etchings. My guess these are from the late 70s.
They are for the three truck goose with both bodies. Also there is a sheet for the #2. Roofs were included for both sets, but no floors. Total, 5 sheets. I also have the HOn3 drawings.
It turns out that there's one sheet for the Pierce Arrow and/or Wayne Bus body, one sheet for the trailer, one sheet for the #2, another sheet that's the roof for the #2, and the 5th sheet is just a piece of brass about 2"x6" with a hole drilled, so I presume it's the roof for the 3-truck goose. No bottoms.
I have no idea what they're worth, so I'll let them go for $25 plus shipping which will probably be around $10. Thanks for looking.
