| COPY. CHRISTR. THOMAS & BROS. LTD. Broad Plain, Bristol. ----------------- Friday, March 15th, 1929. Messrs. Rolls-Royce, Ltd., Conduit St. {Capt. P. R. Strong} , London, W. 1. Dear Sirs, For the attention of Mr. Lappin. Since our conversation on Wednesday last, the writer has ascertained that we are in a position to supply a limited quantity of trimethylene-glycol. If, therefore, your Experimental Department at Derby is still desirous of carrying out tests, we will be pleased to forward supplies on receipt of your instructions. As an anti-freeze, trimethylene-Glycol has a slight advantage over Glycerine in that it has a lower viscosity. In view of the fact, however, that the supply of the former cannot always be guaranteed, we do not recommend its adoption on a large scale. Yours faithfully, (Sgd.) Christr. Thomas & Bros. Ltd. | ||
