I agree it seems weird, but they may have been the only uncommitted units available. Or perhaps there was another pump or water tender at the station, so they were mainly there as troop transports? In addition, I believe these little Karriers were originally designed as hose tenders and towed a trailer pump. Although the unit in the front of the fire station is clearly not towing one, may be the second unit is. It may also have been possible to replace some of the ET equipment with hoses and such, to make one or both of them somewhat effective in a fire fighting role?
Hi Rob, thanks for your reply - yes any one of those scenarios could be the answer. Just come back from a short break in Northumberland and saw the old Alnwick fire station - how strange it reminded me of these little appliance!
