its an early 12g90 casting
it is very nicely ported, the chambers seem to be well worked and it has larger valves.
the stamp reads (now removed)
this is stamped into one of the machined surfaces to the top of the head.
the head is finished in what looks to be its original paint (a dark ish blue/almost green)
does anyone have any ideas of its origins?
is there any chance that this could be a downton item or the likes? long shot i know.
cheers, dan
