Your pics show a nice example of a QSA bearing a highly sought-after clasp. Plus the recipient possibly having an interesting history plus service in interesting units.
First, let me say that I do not consider myself "expert" in ABW research or in-depth general unit knowledge. I just like interpreting rolls and I have my favourite Regiments - plus a good library!
Regarding the reference to the deletion of the "Cape Colony" clasp on several of the Westland related roll pages. The entitlement to the D of M clasp would "knock out" the issue of the CC clasp; Mafeking being in CC.
The MTG roll reflects the D of M clasp only and refers to your man as later being "No.973 of 1st Kitchener's Fighting Scouts".
The KFS roll does not mention the D of M clasp, shows CC/OFS/Tv clasps for "973 Westland" and further comments medal and CC clasp deleted off this roll and issued off that of MTG.
MDMT roll only mentions clasps OFS and Tv, references 1KFS service, MTG and shows recipient received medal.
The other KFS roll (page 264) only shows the "South Africa 1901" clasp entitlement for "973 Westland" and has marginal reference to KFS and MFG.
From all of the above, I would opine that your man Westland's QSA carried the clasps "Defence of Mafeking", "Orange Free State", "Transvaal" and "South Africa 1901".
Of course, I would be happy to see different interpretations of the rolls and corrections.
Dave, you have a very nice medal there.
Many thanks for the information. It is very much appreciated and in my humble opinion took a little expertise to unravel on you part.
At least I have the sought after clasp on the medal. Probably leave it like it is. At least I now know other clasps Mr Westland was entitled to.
Thanks again....reagards Dave
