Hi again JPP!
I filled my A-12 with the xylene (and boy does it smell!) and could form a decent bubble there. Now for the Mk IX I cannot for the life of me find a screw or a hole where to add the fluid. Do you know if one has to break the shellac to remove the upper (or lower?) part of the bubble chamber? I imagine breaking the shellac can make it leak in the future.
Or is there a hidden filling hole somewhere?
Cheers Micke
