They are very good; I really like O&W stuff.
I had an M4 which I sold, and an M5 which was stolen. I currently have a 3095 'Big Pilot' which I wear very often.
They're solidly built, reliable and their finishing is second to none. I bought my 3095 new direct from O&W and my M4 was new at the time from RLT. I suggest you contact O&W directly; Mr Wajs himself is an absolute pleasure to deal with.
