Record levers were only made in that style for one year - 1998 - and they were 9-speed. For 1999 Record went to carbon lever blades.
I'm a little rusty on this stuff now, but I think they also had unique internals that year, and can't be readily upgraded to 10-speed. See here for example:
They certainly look like 1998 levers, and 10-speed didn't arrive until 2000. That could mean one of two things: they've been modified (and I was wrong in what I wrote above) or they're not really 10-speed.
