Sover sent me some pictures of the F2A as he serviced it; this was a unique experience, and made the whole purchase very individual and satisfying. Thank you Sover!
The F3 was a bit beat up - and the seller had not been completely honest about the condition. Anyway, I took it to FixationUK to have it serviced - to my great disappointment, they no longer open up F3s for CLA. All they do is clean from the outside, check that everything is okay, and replace the foams. Wish there was someone like Sover who was willing to service F3s!
Here are pictures of my new beloved toys. The internals of F2A were taken by Sover Wong.
