700 5 digit serial number date

[rfry]

I just picked up a re-barreled 700 so I don't have a letter to go with the receiver number. I am trying to figure out the year for number 59777. Any idea?

"the year for number 59777" March or April, 1963

Thank you! Tried to write a simple thank you but, evidently you have to use 40 characters, thanks again
