Music in Miniature Collectors Set (1 Viewer)

[waleshasgotitall]

We inherited a set of soldiers - all Ducal except for one which is a music in miniature set - says collectors set on the box. There are 5 mounted musicians (all horses are white/cream). The markings on the box state "made in Britain" "this product contains lead and is unsuitable for children" and a gold label with black type on the lid and bottom of each horse which states "music in miniature". There is a label on the edge of the box which has code number MTB/2-A, Type - Scots Greys 1910 written. I have searched on line and can find nothing for "music in miniature" or this set.

Can anyone shed any light on the company that made these figures? Thank you in advance.
