Thanks Raid - very interesting to hear the Swedes used counter-trade to get the ore shipments paid for.
These are lovely lenses and I'm really looking forward to getting mine. It's a LTM screwmount with M adapter but I can easily test focus on the A7 etc.
Film amateur with a few rangefinders - Leica III, M2/M3, Werra 3 and Zeiss Super Ikonta 534/16 medium format.
Apart from that have a Rolleiflex 3.5F, the odd Minolta XD7, Hasselblad 500cm, a Topcon Super D and an Intrepid 5x4 large format (not the half of it but I am clearing them out, honest).
I do all my own black and white developing at home.
