Instrument Air Pump WW2: This air pump was used to pressurise and dry the air in radio and aircraft instruments. It has various markings (see pictures) and although the pump mechanisim works no air is produced. I guess the seals are gone! It is very well made and weighs a considerable amount.

£29 + £12 UK P&P. Please contact me if you require insured postage or wish to have the item sent abroad.
