Yes, thanks, that is prity much what I thought, the cylinders do oscillate, I know it is hard to work out the technical stuff out, with one photo, it is very much like a Major, but it has been made to a very crude level of ability, soldering is not up to my standard, but who ever build it had a level of engineering ability, as the machining is fair. I found it at a Car Boot and I just liked it, the person I bought it off thought it was a Major Boiler with Mecano frame, but I do not think that it is a Major Boiler or Mecano, it is far to crude for that, I am going to Strip it down, Rebuild it and then see if it will Steam.
