Interesting.

I have an original Tempest - easy to cock, just unlatch and turn your wrist.

I bought one of the Turkish ones. To be fair it is well made and solid but almost impossible to cock.
I am not totally feeble but got royally pissed off with having to rest it on my knee, taking a deep breath and
really working at it. After ten shots or so I could not be bothered - and that is a shame as it shoots quite well.

I stripped it down and compared it to the original - many, many compromises - not least the lack of the ability to
screw the end cap on. Why is that a problem? - because you spend far to much time trying to line everything up whilst pushing against the too long spring just to insert the pin which stops the internals from disembowelling.
