This is marked 'SRY' on the reverse for 'Surrey Yeomanry', with the maker's name 'Thomasson & Co.' stamped on the leather retaining strap. There is a broad arrow stamp, together with a faint date stamp (15?) to the inside. Both the MK 5 and 6 pistols would have fitted this.

These calipers, for measuring the circumference of wire and rope, are made of boxwood and brass. The maker's name (as above) is stamped into the piece along with the calibration and there is a small handpunched broad arrow at the base, indicating a Royal Navy issue item.
