This is the older style lanthanum eyepiece. Orion Telescopes current
ad says the new lanthanum are just like the old, except the barrel is chrome plated, but they no longer offer the 10mm, but have replaced it
with the 10.5 mm.
I sort of hate to part with this critter, but I'm trying to raise cash for a MN56 before Mars goes away.
One of other nice features about these eyepieces is setscrew recess in the barrel. You don't have to torque down the setscrew to
keep the eyepiece from falling out.
