COPY OF LABEL ATTACHED BY Mr. HIVES TO U.S.A. BOSCH IGNITION EQUIPMENT TAKEN TO MR. ROYCE FOR INSPECTION.

X.4275 - BOSCH IGNITION X.3485.

The chief point of interest is the fact that this complete set is produced and sold at a profit for 14 dollars. The cost of the R-R Coil alone without ballast is £4.10.0.

We do think there is a lot to be learnt from U.S.A. production of electrical equipment.

We suggest that we fit this set to Goshawk I to see how it behaves. We have the formula from the Bosch Company for the adjustment of the Governor to suit any individual engine.
