Samples received by JSB
As promised, here is the feed back from J.S.B.
JSB have received the samples (from each batch as described above) that I sent, their inspection revealed that the weight differences and head diameters were alright. However the other dimensions and shapes vary, and that it DEFINITELY AFFECTS THE C of G as I sugested.
They will be testing the samples in their tunnel within a week, they will get back with the results !!
It's looking good chap's
