Huckerby}2.3.39 regarding the making of two experimental camshafts for the B.60, and two for the B.80 engine, an alteration is required to this memo in respect of the B.60, which should read as follows:- B.60. Exhaust cam to lead its respective inlet by 113°-15' otherwise the camshaft as EB.4482 and not EB.4268 as stated. The difference in these two camshafts is in respect of distributor driving gear, the former having the latest tooth form and the latter, the original obsolete form.
