I'd guess 581? If you are ML good lift bro... Congrats!
I lift in a different fed (similar single ply rules tho), in the 275s and I am new to the game (first meet next month) but the record in my state will be mine... Some guy just got it up to 600-ish tho... just a small delay....
its not older than yours but last year i broke a bench press record set in 1987.It was at the NYS high school powerlifting championships. I benched 390 n just missed lockin out 405. the record was 385.
