There is no Buxton entry for Guide D.C.Trollip - but there are several Trollips; F.J. (Guide), L.H. (Agent or Guide), H.B. (Agent). Could be relatives? Later, I will have a look at the actual roll in case D.C. was missed.
Scout T.Mellett is confirmed with clasps as illustrated. Unfortunately, no additional information. 393 OFS clasps to FID.
