Lovely shot. :smt023

However, I think it is a Mk1b as the Mk1a did not have the centre rear wing extension over the body.

It's a sight or guide, assisting the pilot to keep station on the aircraft next to them. An aircraft may be missing one from a wing because they usually do not have aircraft formate on them from that side.

Note the slotted leading edge beak for high AOA operations during landing and takeoff.

The device is referred to as a aerobatic sight. It is a attitude indicator, demarcated in 45 and 90 degrees checked against the horizon for orientation. This allows the pilot to perform high G rapid maneuver and quickly check the attitude.

High performance aerobatic aircraft generally are not fitted with gyro stabilised artificial horizons.

Here is a good video showing exactly how the sight is used, go to 10:00 for the start of the routine. You can see the pilot continually checking for reference.
