Neil,
Welcome to the forum and than you for your first post.
I'm not aware of a great deal of information on th IHC, its locations or work. Has anyone else seen any records on this unit?
The QSA roll in WO100/249 does not give too much away.
On page 51 of the roll the note against P Bendel says that he enlisted 23 April 1901. His two clasp medal was issued on 23 October (?) 1908 to 23 White Conduit Street, Islington.
On the supplementary roll on page 125a, his entry is crossed through but the clasps SA01 and SA02 are listed. Are these his clasps?
Regards
David
