re Peregrine and Bensport.

In reply to your memo Sg.{Arthur F. Sidgreaves - MD}4/L/7.7.32, I agree that it is most regrettable that we should have to decrease the stroke of the Peregrine now that we have got one made, but so far as can be seen it is the only way of ensuring interchangeability of the crankshafts, connecting rods, pistons, and cylinder liners of the Peregrine and Bensport engines.

The capacity will be 2290 cc.

E.{Mr Elliott - Chief Engineer}
