What is a Mark X Speedlock action as opposed to a regular Mark X action? Or are all Mark x actions speedlock actions?

No difference in the receiver. The bolt and cocking piece are modified from the Mauser 98 pattern.

Regular Mark X has a standard firing pin drop matching a military Mauser 98.

A speed lock bolt has a shelf cut in the cocking notch that the cocking piece seats in shortening the firing pin fall and consequently the lock time. The firing pin spring is also stiffer, or should be. The cocking piece is modified to allow a standard trigger to work with it and has a flat bottom and longer nose.

I have seen types of bolts in Mark X receivers, but have no idea when they changed.

it's about 1.3cm long flat bottomed block, as opposed to the ~2cm long K shaped military one.

supposed to be faster cocking and firing

And to me, a uselsss concept; Mausers are not built for speed; they are built for reliability.
If you want speed, get a Remington 788.

I agree. I've done some decent shooting with my "super slow" M96 Mausers and a two-stage military trigger.

My concern is because I purchased a Wisner 3 position safety for one and the destructions are different for the speedlock version. Hence I needed to know which one I have.

Oh, just measure and locate the position/location of the front of the cocking piece; that is what is important. That is where the Wisner wing contacts and pulls it back.

Don't feed the trolls

Thank you very much.
