New Inline-6 engines? Don't exist. Your best bet may be to buy a used M337 and find someone who knows their way around them. LOM is also regularly present at AERO Friedrichshafen, so maybe try there next year.
I see you're from Germany. There's a fly-in for Czechoslovak airplanes in Roudnice nad Labem, Czechia from 27-29 June. Not too far from the German border. Last year, the general manager of LOM's piston engine department was there as well. Not sure if they are present every year, but I guess that would be a good opportunity to talk to someone in charge.
