This product is a set of two classic streetcars, Desire St. and Powell & Mason Sts, from the San Francisco Municipal. They are HO-scale rolling stock dummies made of plastic and diecast metal, with a true HO-scale 1:87 gauge. They are pre-built and ready to go, with a non-powered dummy unit power supply. The streetcars were manufactured by Bachmann/Readers Digest Promo in China during the late 80's to early 90's. Suitable for everyone, these streetcars are colored green and are not a custom bundle nor a modified item.
