The SR (left) is long reach. Haven't seen a long-reach SR lever recently; hence, that is a bit of an oddity.

That said, the lever on the right is an NR with drillium, but I cannot tell whether its a short or long reach variant. At any rate, the early long-reach versions are supposedly quite rare, but I've found that to be anything but the case: Most every NR lever I've found has been long-reach (not to say I haven't found short-reach, but it has been in the minority).
