|Description||The folders consist of exchanges with Government Committees and research establishments (mainly R.A.E Farnborough) and with Metropolitan-Vickers (Manhester) re feasibility, manufacture and testing of photo-electric and proximity fuzes. (see letters from H.T. Tizard in D.5 and D.12 about arrangements for Blackett's work on these devices).|
The material is presented chronologically as far as possible. Blackett's very bulky folders have been split into smaller units for ease of reference.
