Anyone ever seen a dual artificial horizon in one case?
The label shows 6A/NIV. 'NIV' was/is the acronym for 'Not in Vocabulary' i.e not formally provisioned so not assigned a 'proper' section/reference, and probably pre-dates NSNs. I suspect that the item is a non-standard item and as such would be unlikely to be fitted to an aircraft unless it was on a trial fit: I certainly wouldn't have expected to see it as part of the general stock of aircraft instruments.
Agree with 4mastacker except I'd add to this...
that there are more reasons for NIV. If the ident label was accidentally removed and a glance through the Rate Book (showing my age there) didn't come up with an NSN, then stores wallahs would be told to append NIV after (the rather obvious, in this case) 6A, and return to, usually, 14MU.
14MU would then look to specialist workshops at 3rd line, who would occasionally get a crate of NIVs to assess.
The NIV suffix would be sufficient to prevent it being issued to front line or fitted to an aircraft.
I followed the link to the other site (very interesting, never been there before) and it was mentioned that Strathallan Air Museum was printed on the paperwork. At the time, (1977) Strathallan's pitot-static systems were maintained by MoD (NARO) 3rd line workshops. (Sssschh!! they weren't charged, the instrument fitters regarded it as a pleasure to get to work on Lancasters and the like
). Hence, it would not be a contradiction for an MoD conditioning label to be attached to a Strathallan instrument.

Its not from a Jindivik Director aircraft by any chance?
I seem to recall reading somewhere that when the Jindivik came into service they used a Meteor trainer with a controller in the back seat in case they lost signal from Llanbedr.
A quick goggle reveals that at least one of the Sea Vixens at Llanbedr came from Eagle, so possibly also used as a Director aircraft.

The top left of the repair tag shows what could be a serial number ( popular format) 24KHI/56. The /56 usually denotes the year of manufacture. Could that narrow it down a bit.
