| XS78360 EFC3/T26.11.26. To Mr. Brock for Mr. Watson. 20 HP. DYNAMO. Your ref. Sales 89.K6. of the 24th. We are returning this machine to you after examining same. It is true there is a slight stickiness of the negative brush which may have been rather worse at some time of running on the chassis, because there is a certain amount of indication of this brush having sparked rather badly. Though we cannot assert definitely that this was the cause of the solder running, we think it may have been the cause. We can, however, definitely assert that with the brush setting and output of this machine and everything in O.K. order, the machine could not possibly have run its solder simply by peculiar conditions of running which the customer may have practised.
