(This cable was dated August 21) I quote below a memo from L.G. Ringholz: "Subject: Monarch Lathes for Turning 40 Millimeter 80" Long Barrel "Some time ago, I mentioned the fact that one lathe would be sufficient to handle proposed production on above subject component, the following will confirm same: "99.6 minutes required for all turning operations "10.9 minutes required for handling "110.5 total minutes required to complete machine one barrel."
