Yes, Dickson built a 28 three barrelled guns, with two triggers (the first trigger being a single-trigger for two barrels) and three triggers in a variety of 12, 20 and 16 bore.
Boss built a three barrelled gun with a single trigger. There were also three-barrelled guns by Westley Richards and E. C. Green.
There is of course some superb craftsmanship on those guns but to me the Manton name looks odd on such modern material? Good luck to the guys behind this venture, if they can bring something good to the gun trade, then great.
