One little question: I think to remember that for the 2914 there were different configurations & combinations of hands possible & described:
( Pretty sure, it was a thread 2011), specifically samples with the "typical"
broad arrow hand, and also a straight second hand in several..
Also remember, that you have posted 2914s (Pakistani Air Force ?),
where there also were the broad arrow configurations.
Not that easy to make all the homework, but I guess, I also have been at least
recently very lucky to find a very nice 2914-2 !
Here just 2 quick pics with kind greetings.

Sending greetings from my CK 2914-2 to your 2914-6
Anyway, am really happy about this lucky find !
Best, hs
