More Aluminium Solder.
To those who are always anxious to secure something in the nature of a solder which can be satisfactorily used on aluminium, we would suggest that they should write to Brown Brothers, Ltd., 22-34, Great Eastern Street, E.G., and make a request for a sample of Mackenzie's aluminium solder, for which great things are claimed. We have caused a sample of this preparation to be tested with considerable success. No special flux is necessary, and only moderate heat is required to melt the solder—a very important point when aluminium is being " doctored."
Lamps for Commercial-motor Vehicles.
We are interested to have received a useful list of wellmade lamps for road vehicles from Messrs. A. W. Sanderson and Co., 206, Barford Street, Birmingham. The bulk of this maker's business consists of the manufacture of lamps for railway and colliery use, so that it may fairly be assumed that the workmanship embodied in these products is calculated to stand the hardest possible wear. The user of a steam wagon or tractor or a petrol-driven van is not in the same foolish position as the private owner who habitually carries £50 or £.60 worth of headlamps on that part of his car which, some day, may be the first thing to hit a brick wall. Commercial-vehicle users as a rule have more sense than that, and lamps are generally kept well out of the way; nevertheless in a commercialmotor garage these fittings meet with very short shrift and require to be of a very substantial nature; they must not show signs of falling to pieces because of excessive road vibration. Sanderson's have made lamps for traction
engines for many years and are now beginning to specialize in similar patterns for all classes of commercial vehicles. If not exactly beautiful to look upon, they are, at least, substantial and calculated long to withstand the rough usage to which all detachable fittings of a motor are subjected on heavy commercial work.
