M--- 172 BY.13/G.22.12.37. 25/30 HP. CLUTCHES. RE: BRONZE TYPE OF FRICTION FACING. Referring to Rm{William Robotham - Chief Engineer}/GWH.{George W. Hancock - Head Chateauroux}18/M.21.12.37. there are some 50 pairs of these in our Stores, at Derby, and in future N. must indent for these in the usual way. We supplied 20 sets in the first place to get results, the results are good enough for us to carry on and use this type of plate for replacement purposes on the 25/30, and we are arranging to order sufficient of the plates to keep a stock at Derby for replacement purposes. | ||
