Aeroplane Monthly 1982-12
The first aircraft had not been with the squadron a week before station workshops were called upon to make a set of 6ft ladders to serve this entry point. The photograph of a visiting MkIII, K8947 at Linton in early 1939 shows both entry ladders in position. This aircraft was a rarity at the time as all three turrets were fitted and the ventral is seen drooping a little.
The first production Viima II, Finnish Air Force serial Vl-3, later G-BAAY, seen at Joroinen in 1939.
The SZ-4 has been preserved in flying condition by the Finnish Air Force.
