| Lo F.{Mr Friese} c. to. Wor.{Arthur Wormald - General Works Manager} X4300. Hs{Lord Ernest Hives - Chair}6/NT.20.3.31 TROPIC-AIRE HEATERS. Replying to F.21/JL.10.3.31. When I was in U.S.A. I examined the Tropic-Aire heaters and also other makes, and I purchased one which is used by the Packard which I think is better than the Tropic- Aire. This apparatus will give us all the information we require and therefore we are returning to you the two Tropic- Aire heaters you sent to Derby as they are of no use to us.
