FWB Where is my sleeve?

I thought all FWB300 had a long barrel sleeve? This gun is so front heavy with long barrel/sleeve, it's almost better this way!

There was a surprising amount of variation in those sleeves over the years. Among the guns I have:

+ 300S Junior: barrel 320mm long, with no sleeve ("naked" barrel is 15mm in diameter on all these guns).
+ 300 Match: barrel 445mm long, with a constant-diameter sleeve of 20mm diameter. Mine is unusual in that the sleeve is not epoxied on, I can enjoy shooting it with or without the extra weight.
+ Early 300S Match: barrel 395mm long. Rear part of the sleeve 18mm diameter, and the fatter front part is 22mm.
+ Later 300S Universal: barrel 395mm long. Rear part of sleeve 18mm diameter, front part is shorter but fatter at 23.5mm.
