Heaters you say? I want one!
From what I've read the crew were equipped with heating lines, plug-in circuits in their clothing (I'm assuming) that kept the crew warm, rather than heaters, but it would have made a big difference on long cold patrols.
Here's a quote from Mr Eric Brown, whom is a delight at describing these things.
"My first impression of the Albacore was one of size. It seemed so much larger than its predecessor and those thick wings and that massive undercarriage, let alone the wealth of struts and bracing wires, were eloquent of the sort of performance that one might expect. Of course, it's beautifully cowled Taurus offered a lot more power than the Pegasus of the old Stringbag but I wondered how much of this was absorbed in compensating for the built-in drag."
"A single-bay all-metal biplane, the Albacore was essentially simple in concept. Its equi-span fabric covered wings carried ailerons on both top and bottom planes and hydraulically operated flaps on the inboard portion of each lower mainplane. Automatic slats had originally been incorporated in the leading edges of the outboard portions of the upper mainplanes, but their unsatisfactory characteristics had led to their deletion. The light alloy monocoque fuselage incorporated steel-tube engine mounting, centre section and tail bay, the centre section being bolted to the monocoque decking between the cockpits. The fixed tail surfaces were of stressed skin construction with all movable control surfaces were fabric covered."
"After clambering into the Albacore's cockpit, which was a long way off the ground, I found no major departure from the essentially simple theme that characterised the entire aircraft, the layout being very neat and clinical."
Brown goes on and describes it as a well-behaved and likeable aircraft forgiving of mistakes, but admits that as he was trained as a fighter pilot his attitude towards its pedestrian performance and sedate manoeuvrability is biased, although he states that its pilots liked its handling, but decried its lack of manoeuvrability.
