Rob,
The Birmingham Mint purchased J R Gaunt in 1973 and shortly afterwards (45 years ago) they manufactured and marketed a set of 52 Line Infantry Regiment cap badges with commemorative silver medallions. The badges and medallions were described as a “Tribute to the 52 Time Honoured Regiments of the Line that have passed into legend” and were sold in a ‘Limited Edition’ of 3000 sets in monthly instalments to collectors.
It would seem possible that Gaunt dies were used in the production of many of the badges in the set. The only reason the badges have sliders was that the set was complemented by a military style wooden chest with two fitted drawers to hold the badges and medallions.
