The A50 is a smaller diameter. The stroke is the same so if you need an A65 barrel and come across an A50 then it may be possible to get it bored out.

Hi,
The A50 barrel is shorter than the A65, the A50 skirts are longer.

Hi,
I have surplus, a later A65 barrel it has been recently bored and honed to +20 and the upper fin repaired. The repair isn't noticeable when the head is in place.

Best wishes...
