Sadly Bowser quit the kit steam engines and sold all the parts n stuff. I have several, and I built at least 7 of the Old Lady 2-8-0's for my dad. I have a Challenger, a PRR 2-10-0 a Southern 2-10-2, a USRA 4-8-2 and a PRR K4 that I modified into a K3, which Norfolk & Western bought 5 of during WWII.Dudes I am kinda bummed,got out my Bowser 4-6-0 and discovered the cylinder block has Zinc pest! I smeard some epoxy on the cylinders to stabilize them while I track down a new cylinder block.The Bowser website does not list the part as available nor does the bay,they do have blocks for the E-6 Atlantic and the K-4 Pacific so I hope one of those will work..
