Silver tone metal buckle with colorful enamel by Siskiyou Buckle Co. from 1984. Depicts a train passing in front of mountains.  The sky, mountains, and grass have all been colorfully enameled..  The back gives a blurb of the historical importance of the railroads and has a model number of A-29.

It is in great condition. It measures approximately 3-1/4" x 2" and fits a 1-3/4" wide belt.

I have several other belt buckles for the train enthusiast in your life listed.  I will combine shipping if you purchase more than 1 of them.
