Hello Mel, Jackie, and my friend Westoe( and our Lass)
Yes it is for certain that he was with the Waterlow and Layton section, though before the split, he and his sister Lavinia ( who was it appears, worked in Binding & Velum work) had already been there for sometime.
If you have the time, Mel, would appreciate any info, as only knew about him from a 'one-liner' in Grand Aunty's book ( The Story of a Saxon Family ) and unfortunately all her papers and the family albums disappeared, even though the Executor was due to place them all with Exeter Archives !!
Best
John
