Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Ben, I have that 25 on my watch list as well. As I mentioned in my intro, my very first steam engine was a Jensen 75 (approx. mid-sixties.) The beautiful brick-embossed firebox resembled an overdone fritter after the very first steaming. I was disappointed, and I eventually gave the engine away. I've been on the lookout for a 25 from that same general era, with the slimmer handles, and ungrooved flywheel.

I kind of wonder why Jensen has never addressed this issue through the years. They must have had to use a thinner metal when they went to the embossed design, but you think they might have added some insulation, similar to what Stuart did with the 500 series boilers. That thin metal really conducts the heat to the outer coating.

Good luck with the bidding! I'm at a disadvantage since I just purchased a 55, and I think I may have overpaid. However, it's a brass-tag model, and was upgraded with a generator. But my engine budget is feeling the pinch.
