These pistons will shortly be going on production. We think we have previously mentioned that owing to these pistons not having split skirts, it is essential that the cylinder bore limits should be held to closely. We know that experiments have recently been carried out in getting a fine finish to the bores, and we should be interested to know what at present is considered to be the commercial bore limit which can be maintained.
