All Brass Hot Air Engine

Here is a Hot Air Engine that was built in 1995 by R. Perlberg. It was sold at the annual "Cabin Fever Expo" 24th anniversary model show and auction in Lebanon, PA this weekend, of which I been going to for the past 24 years.
A little polishing and it looks great. It also runs great .
PS. I never know which category to list my posts on so I will just say model cars and let the experts at CW put it in the proper category.
