Dear Sirs, In reply to yours of the 27th January, EPC.1/AD, re moulded battery containers for Phantom II chassis, we do not think that your suggestion will weaken the handle at all and we have no objection to it. You will recall however, that we are not moulding these boxes, we believe you arranged the supply with the Chloride Co. and we obtain these from the same suppliers and if they and the Chloride Co. and yourselves have no objection to the proposed change, we have no objection. While on this subject, we would say that had we made these boxes we would have made the brass insert as per the enclosed sketch and we think it would be much better as we consider the present one to be definitely bad. We cast the brass insert into lead and then mould this into the container. With this arrangement only the lead is exposed to the acid instead as at present, the brass and there has been corrosion noticed on some of the containers owing to the brass being attacked. Lead-plated brass is next door to being useless. If you agree, perhaps you will say that you wish them moulded like this in future. Yours faithfully, G.R.N. Minchin | ||
