Most interested to see this thread. Cannot state when, it was long ago, but one of the first sets of "toy soldiers" I bought as an adult was from the Paxton-Sheriff "Union Jacks" range. I got the set of an officer and 5 grenadiers of the 26th regiment of foot , The Cameronians. The grenadiers form a firing line. The cost was the princely sum of £18.50. They were from Series 5, which consisted of 9 different regiments that had fought at either Sheriffmuir or Preston in the 1715 Jacobite rebellion.
The Union Jacks ranges, as described in the Paxton-Sheriff leaflet I have, are of an officer and 5 grenadiers of British regiments, plus some drummers and fifers.The various series covered the following time periods:
Series 1. 1751, was all grenadiers with serial numbers beginning TSG1.
Series 1/A 1751 was fifers and drummers,2 of each in a set ,all had serial numbers beginning TSG/A.
Series 2. 1775 grenadiers. Serial numbers begin TSG2.
Series 3. 1775 Highlander grenadiers. Serial numbers begin TSG3.
Series 4. 1793/94 grenadiers in Martinique and St. Domingo. Serial numbers begin TSG4.
Series 5. 1715 grenadiers from the battles of Sheriffmuir and Preston figures.
I wish that my finances had been better many years ago, and my interest in military miniatures stronger, as I would have bought more.
Must try to take a photograph and post up the set I have.
