I should have recalled that the towing vehicle for this fine restoration was a Matador. I served in a British HAA Regt RA (1950-1952) and we hauled our mobile 3.7's from Gravesend, Kent to Sennybridge nr Brecon in Wales to attend the annual practice firing camp, where the 3.7in AA guns were fired in a field artillery role. The rest of the year we trained and deployed to permanent gunsites as part of ADGB
