Should be
20M3/?
Is the frame/frame plate also stamped 130319?
In a previous thread, you said that you "
Have a 1969 roadster with the same oil tank."as an 'S' Type...
Dang, that looks great!

... however, 20M3/130319/P is not only too early for it to be a Roadster as a Roadster or 'S' Type (also too early) with the same (central) oil tank should have a 20M3
S (camshaft points) engine number prefix and neither Fastback nor 'R' Type in production at that time had the 'central' oil tank. A 20M3 engine should have a points housing behind the cylinders.
I cannot identify that number. Is it a stamped number or a casting number (so above the surface of the casting)?
The gearbox would normally have a matching (130319) number stamped across the top mounting lug.
I assume that number is actually on the cylinder block and is the
casting number for the 750 block.
If for whatever reason, it has a central oil tank...
