Some very nice equipment there Wojtek, and obviously well cared for. I notice you have some of the plastic measuring cups like mine - I got some from the nurse when I was in hospital last year - very useful for measuring paint and thinners. I also noticed the Tamiya masking tape refill - they aren't available here, I can only get the tape in the dispenser, which, apart from costing more, is a waste of the dispenser when it's empty!
BTW, do you know anything about the Aztec system of three different nozzles on some of their airbrushes? I know the make, as they used to supply them when I was with Kodak, with the Kodak badge on them, and they were quite expensive, and considered up-market about 20 years ago. But I don't know about interchangeable nozzles. I have seen a Aztec at a very good price which has this feature. If it has a fine-line capability, I might get one, as the 'brushes I use at the moment only go down to about 3 mm.
This particular one has a metal chamber, but the plastic body, and is single action. But, for the price being asked, I don't mind. I have also seen another brush, very like an Iwata, but not a cheap copy, that is on offer at half price - £30 - and has a 0.3mm nozzle, which I think would give a fine line about 1mm to 1.5mm wide. This is a gravity feed, dual action, so more control, but realtively small paint volume.
