It comes from a different set of foundry patterns to the two die cast cases that I have, One needs work on the cam bearing housing as it has a crack in it, the other one is ony fit to melt down and recast as a new crankcase.
From the look of the two die cast cases they have been cast from different foundry patterns from each other.
It make me wonder how many foundy patterns were used for Nippy engines.
The pressure fed Speedy crankcase that sold not so long ago on ebay was sand cast. That had been overstamped with a revised engine number.
