here is some info about 9,4 mm dutch service revolver. this will tell you how to tell the difference between the original antique and later English Vickers made gun which is not classed antique in canada.
In 1891 a smaller and lighter revolver designed by Captain F W H Kuhn was adopted for the KNIL and J F J Bar were contracted to supply the parts, to be finished and assembled at the Small Arms Arsenal in the Netherlands. The first guns were finished by the end of 1894 and delivered in 1895. The total production numbered 3754.
In 1909 it was found that more guns were needed, but Bar no longer made arms, and the contract was placed with L Wittich for a further 2200 guns.
In 1919 it was decided to equip the Field Police with M91 revolvers and in 1920 the Colonial Ministry placed an order through the Dutch represntatives of the British arms company, Vickers. In fact it appears that the parts for these guns were not actually made by Vickers, but organised by them - using smaller firms based in and around Birmingham as suppliers. This may be the explanation for the quality of the product (Vickers had a reputation for weapons manufacture) which proved to be unacceptable, and the guns were sent to Fabrique National in Belgium for refinishing, finally reaching the Dutch East Indies in 1922.
The standard model had an overall length of 9" and a barrel length of 4.5"
These guns, numbering 5830 are known as Vickers guns and are identifiable by the crowned W stamp on the right side of the frame in front of the cylinder, and by the shape of the shallow recess (to accomodate the end of the loading gate) above the right grip (on Vickers guns it has a rounded profile).
Some guns that showed an adverse reaction to the introduction of Smokeless powder also had a reinforcing section added to the top of the recoil shield
