| W/S.. To Sg.{Arthur F. Sidgreaves - MD} from Hs.{Lord Ernest Hives - Chair} 44555 Hs{Lord Ernest Hives - Chair}1/LG5.11.27. RE. DIPPERS. Sg{Arthur F. Sidgreaves - MD}9/M4.11.27. X 1357 We have been in communication with Messrs. Lucas on this matter and they have pointed out that they cannot fit the dipping reflectors to their latest type of lamp. As we are certain to standardise the new lamp very shortly, this is rather unfortunate. We are writing to them again however, to find out whether it is intended in the future to make this lamp suitable for a dipping reflector. In the meantime we will try out the scheme on the old standard lamp. Hs.{Lord Ernest Hives - Chair} | ||
