Now, the cylinder is cleaned and dismantled. VERY interessting.
At first: it‘s a LOCKHEED LB16HC08 M 16. The „M“ is the mystery, it‘s stamped over two other letters.
Dismantled the seals are 15.7mm
That‘s not unusual- but now: there are massive metalflakes in the seals!
So it‘s worth for a more detailed look. There are a lot of repairkits available (from 2.50 EUR to 6.00 EUR) and if it show no scratches inside I‘ll rebuild it.
I‘ve ordered some repairkits and now I‘ll clean and inspect it. The worry: what‘s about the slavecylinder, are there metallflakes too?
After the rebuild I‘ll give further information.
