Opinion on this Double red mk4

[sinhang917]

I am considering a mk4 drsd from Matt Bain, they mentioned the watch is all original and period correct and lume didnt react under UV. May I ask you guys opinion about this drsd and see if anything is weird.

I am looking for condition one with period correct matching (case , dial ,insert , bezel, caseback, no re-cut, no relume (relume on hands is acceptable for me)

Serial :50xxxxx
insert : mk3
bracelet: 93150 580 end link stamped code k1 (so should drsd match with 585 endlink ?and k1 is 1986, so i think this is not exact correct but acceptable i guess )
Datewheel: silver, open 6,9 16 and closed 26
Caseback has serial number matching inside.

Million thanks!
