speedmaster clasp repair

I'm looking to repair this deployment clasp. It's on a 20 mm strap which I believe makes the clasp a 20 mm clasp? The issue is that the clasp does not stay clasped. I believe this is usually due to a spring failure. Ideally I'd like to know how I can find the part number of this spring and where to buy it so that I may replace it myself. Any help here would be greatly appreciated. I tried searching and could not find a relevant question for this particular model - apologies if I'm asking a question that has already been answered a million times.

not sure why the images aren't showing up but here are the links

the 20mm deploy strap has an 18mm clasp.
I have never seen springs available for these. I am not sure if they are serviceable.
you may have to go to the authorized dealer for such a thing if it is serviceable...
ofrei sells parts. id start there, they are running out of parts though.
good luck.

it may also have some gunk or lint trapped in there, maybe a good cleaning would help it.
again, good luck.
oh, and I have seen fake ones rust inside which makes them jam up, the 2 bars that move look uneven in your second pic. did you buy this new?
see my old post here for how to tell a fake one from real.
i need to update it with another version i found but it should be suffice for your purposes.

Appreciate the responses and thank you!
It's for sure a real watch and bought from a reputable and certified dealer.
I probably don't care for it as well as I should as evidence by the shape the clasp is in, but the watch means a lot to me as it was a gift from my brother (who knows quite a lot about watches) after my first cancer treatment.
I've also learned a thing or two since then and this would be a pretty impressive fake if it were one.
