The second number indicates the year within the decade. Your 830 Record was probably made in the 70s and has a serial number beginning with 1. My 910 was made in 1983 and the serial number begins with 23. So yes, adding 60 to the first two digits is accurate.
That would have been good info to have a year ago when I emailed Bernina and got the date of manufacturer.
I've kept it for my files.
