Within the 2000 series the cylinder and barrel dimensions are slightly variable, as is the shape of the cocking link. The rare inclusion of a walnut grip is yet another variable. So to date we know of SN 2003 and 2006 that have the wooden grip, and SN 2004 and 2012 that were not fitted with such a grip. All these guns were apparently made on an ad hoc basis, and would have been largely hand built. There are evidently a few more out there to be discovered.
