A Taylor brother of some form I believe, though he does include WK in his paper?.
There was a Donald Beckley who had a connection with Freshwater (see address on the pamphlets), though possibly a bit young? https://www.theseaviewcollection.co.uk/products/donald-beckley-seaview-isle-of-wight-pottery-green-pot
I doubt that this brother was in the Taylor meetings as he refers to Sunday Schools which, by the 1940s, would not have been characteristic of them. It is more likely he was with KLC brethren as in issue #21 (1946) under "News of the brethren" he mentions T. E. Noall. This must be Thomas 'Tommy' Edward Noall (1913-85) who was local at Plum Lane when Edwin Cross was there. C. Martin of Redruth (Cornwall) would probably be related to Sydney Robert Martin (1902-89) who moved from there to TW. Redruth was one of the TW meetings that reunited with KLC in 1940. William Henry V. Blewett (1918-86) was from Devon. C. W. Kemp might be the late Charles Kemp of Catford/Greenwich? A. Dimery may be Albert Dimery who I understand was in a Parachute regiment. Also, I suggest H.G.M whose article appeared in another issue might be H. G. Moss who wrote the Notes on Revelation.
Apparently, D. Beckley was 'Don' Beckley. Donald Edgar Beckley (1914-97) married Alberta Dorothea Stuart (1915-2002) in 1941 which would suggest that he was the Don Beckley who ran Seaview Pottery on the Isle of Wight from 1956-81. According to Lisa Dowden, co-author of A Century of Ceramics, "My very first phone call was to Don Beckley of Seaview Pottery, and we were fortunate to be able to meet him and his wife Berta soon after."
