Gratiot Valley Model Railroad Club question about a building construction.

I saw this post from the Gratiot Valley Model Railroad Club, and was trying to locate the material used to construct this building. Does anyone know what this is constructed with?

Thank you,

Kurt

It’s made from a Bachmann Trade Tower kit. It’s out of production, but there’s one on ebay now (current bid: $71.00), will probably go for more.

Plastic huh??? Looks nice!

Thanks,

Kurt
