I know I posted the 1912 Ives as my oldest locomotive... but I guess I do have one that is older, although it is in need of restoration and is a bit too large to be considered "Tinplate". It is a Class C Cagney of 1899 vintage. I know it doesn't look like much, but the important parts are there and it is in line for restoration after I finish another live steam restoration that is in the shop. It will run again - I've rebuilt worse:
