Hi Klaus,
That's ace! Thanks very much for replying.
Looks to be the right one, i count 8 fins and 70 + bore, sounds like A 10 to me, i am looking closely at one of the images there and i think i can see a part number engraved on the edge 67-258 which seems about right. looking through a parts book it mentions 67-253 for A 10 plunger engines from 1950 to 1953.
I am just wondering if we can get an esteemed colleague on the forum to concur.
if its correct, then yes Klaus i am interested.
Regards,
Brad
