If I remember correctly, many Noricas (not the old leather sealed ones) and Beeman's Norica clones also use a 26mm seal.
The old BSF 55/60 also has a 26mm diameter, but uses a leather seal.
I see WW does a meteor conversion 26mm, Ive already got an m6 threaded piston so some of these conversions look interesting, at the moment I’m using a seal hw but see some HWs have a wee bit of a dome rather than smashing the lip into the plug
