Anglia/Consul engine & gearbox numbers

[cantus]

I am restoring an old 1959 TVR Grantura original fitted with a Ford Anglia engine.
I think the engine or the cilinderhead is replaced many years ago because the cilinderhead says 105E and the engine says 109E.
To make it more difficult, the gearbox says 113E.
Is this OK? Could this be original ?

please advise

kind regards
