Head Identification, Iron with stumps?

[Harryc208]

Hello all!

dug this head out of the shed the other day, never seen one  before so wondering if sombody can shine the light,

It has a smaller finned area than the usual a7 a10 heads, and its got stumps where the exhausts usualy push in.

Was wondering if it was a longstroke a7 head perhaps?

Under the inlet port its stamped 45-2810       The 8 could be a 6, or even a badly formed 0, and the last 0 could possibly be a 6,
                                           K301A

Anyways heres the pictures





Any help much apreciated.

G'day Harry,
                looks to be a early A10 or short stroke A7 '51-'53 that has had "stumps" put in like Trihards.

Hi Harry,

I think it's off an Ariel.

Harry,
               Beezageeza is right, it is a Huntmaster head.
