Another vote for the large action (Westley-Richards)Francotte-Martini - much rarer, and classier than the ubiquitous Mk II. And with that takedown mechanism, much easier to clean, repair and maintain. Example? I'll probably have one along at the IHAM this year in Bisley, maybe more than one... Hmmm - and there is 1 person I know of having solidworks drawings.
