Dur……

I’ve been looking over some AP1660A circuits and I’ve just realised that the ‘Mid Turret’ that is referred to as being interlocked is the one that drops below the aircraft. This is because the circuits I was looking at are for early MKI aircraft which did not have a dorsal (mid-top) turret. Clearly you would expect the gas to easily enter the mid lower and rear turrets.

Only 7 months late perhaps, but it does actually help to date the circuits!
