Don’t get too excited yet. The parts are not NOS but came as part of a “little transaction” involving R bits and associated memorabilia that I made many years ago. The fact that they are from an engine that I suppose must have once ran but for some reason unnown to me required them to be removed may mean that they may not now be servicable. I didn’t take a lot of notice of the condition and just put the parts into the spider inhabited abyss where hopefully they still reside safely. I seem to remember that one of the rods looked as if it had been heated up. Pretty sure the cams were in good nick though.
I’ll send some piccies and further details as I say, on my return.
