Mike, I think Bill may be referrring to the original Apex T50 (piston) 1st = stage which was a silicone oil filled Mk10 copy (except for the lack a = port in the end of the turret). I first saw these in Australia in about = 1991.=20 These things worked ok but the plastic cap on the end that held in the = silicone oil used to always crack and leak.=20 The original T50 second stage was esssentially the same as the TX50 = without the "heat transfer" sleeve located on the outlet port.
