| X.3y21. Extract from R1/G.2.12.19 X.2748. RE PISTONS? X.3754. X.3721 I have not seen the suggestion for Mr. Barrington's Zephyr split pistons. I ought to have done so even if the matter could not bear the time of a post to me. The descriptive advice of what you are doing should be sent parallel with the instructions to the shops because we have been over the Zephyr type just lately with a view of splitting or re-testing the combination piston with modification. So far we have found nothing quite worth sending you. | ||
