Re: 1936 VB Inlet valve guide oil feed pipe

Re: Wanted - Rigid rear hub - Type 5 & top fork yoke.

I received a response from the seller - so dimensions are what he gave me.
7 3/8 inch between the fork centres - 2 1/32 inch to head stock centre line to the fork leg centre line.
Guess this makes the item H2 - 46 1946 - 1948 to anyone wanting one.
