"B" banger. Hard to get parts for them. Worked with the lads in Wiking in .de a few years back and they seemed to be the "go to" guys for 76 support in Europe and they really struggled to get parts and were "manufacturing" a lot "in house".
For a small shop it was pretty impressive and their own A++ mostly had more than 20K hours on them.
Never really worked on 76's but in passing to me they all seemed to individual and "hand made". Just sayin'.
