Swampy Jenson Model 75 Steam Engine

Found this at an antique store in Hannibal, MO. Looked like it had been buried in a swamp for years, covered in algae, rust and calcium. It cleaned up all right but also lost most of the nickel plating in the process (I soaked it in CLR for too long) but thats alright with me because now at least it runs. I found it has at least one boiler leak so I may just run this one on compressed air in the future.
