Hi Bart, Is yours missing? wore out? We have some very talented people here that may be able to make a part if one cannot be found...
Hi Nick I am new at this. I have to figure out how to get a hold of you. There is a video of a model 45 running on Google under Jensen Model 45 Vertical Steam engine. The cylinder is missing on mine. It has a closed end, and the spring loaded mounting screw is missing too. Did I read correctly that one might be fabricated? Perhaps Jensen could supply me with the specifics. I got a few parts from them, bit as you can imagine, they haven't built one for a long time. Bart1353
