This little H.K. Porter 0-4-0T belonged to the Father of a close friend of my Mother, but Clyde's "Backyard" was about 6 acres. It also helped that Clyde was a machinist by trade, with his own machine shop business. Clyde had a Love of old machinery, and bought the Porter, a Heisler(3 truck) and a large collection of antique machinery at scrap value for most of it.
The Little Porter was the first live steam throttle I ever pulled. While I did get to see it before Clyde's passing, my only opportunity to run it, came at the Final Steam up in his honor, after his passing. Clyde's collection also included several steam farm tractors, and stationary "Donkeys", and a Stanley Steamer automobile. His collection was nothing short of a medium size museum.
The Bachmann #1 Gauge Saddle tank Porter(long out of production), is a model of Clyde's locomotive, and I managed to find 2 of them. A couple years ago, I put together some track, transformer and cars(Clyde never had any rolling stock), wrapped it up, and a few days before Christmas, stopped by to "Visit" Linda and Arnie. When Linda opened that package and recognized the Porter as her Father's, she started crying, it had to be one of the Best and most memorable moments that I have had in this hobby.
Unfortunately, the family was not able to keep Clyde's collection, and the Porter was sold to a Private individual in Kelowna, BC who has given Linda an invitation to come see "Her Dad's Porter" whenever she likes. it sounds like the new owner is very personable, and will take Good care of the little Porter.
You can have a locomotive in your backyard(check local ordinances FIRST!!!!), Clyde's little Porter's boiler did not have a current certificate, and he had fitted it with an 80 PSI safety valve, because of that reason, but it still brought many people, many smiles, not the least of which was mine.
