Markings and Variations
It is a 1908 Pieper Bayard Pocket Pistol in .25 cal. I guess more accurately, it is in 6.35 mm, as stamped on the slide or what we know as the.25
The definition of a variant is to some extent arbitrary, since most guns undergo small changes over time but, when a change makes a noticeable difference in the external appearance of a gun, we may consider it a legitimate variant. In the case of the Bayard, there are two variants of the 7.65mm version as well as of the .380 (9mm) version, and the 6.35mm version differs substantially enough from the other two to be considered a variant in and of itself.
The 7.65mm and .380 (9mm) Bayard Pocket Pistol
The Bayard was first produced in 7.65mm (.32 ACP)--this is the ammunition for which the design was originally intended, since Clarus filed his first patent before the 6.35mm Browning cartridge was available. 6.35mm ammunition came on the market late in 1906 with the advent of the 1906 FN Browning pistol; it was introduced in the U.S. in 1908 as the .25 ACP. The 9mm Browning Short (.380 ACP) did not appear until the advent of the 1908 Colt in .380 caliber. However, it is likely that by the time the first Bayard pistol appeared in 7.65mm, Pieper was already planning to make the gun available in other calibers. As stated above, the best evidence we have shows that the .380 (9mm) version became available for sale in early 1911.
6.35mm Pieper Bayard
The 6.35mm Bayard barrel is integral with the frame--it it not a rifled sleeve pressed into the frame, as on the 7.65mm and 9mm versions. The front portion of the trigger guard curves back somewhat before mating with the underside of the barrel. Most of the upper portion of the slide is more narrow than the lower portion where it mates with the frame. The 6.35mm Bayard is just over an ounce lighter than the second variant 7.65mm or .380 (9mm) versions. Since there is less room on the barrel portion of the frame, the inscription was moved to the rear of the frame, over the grip plates, and the horse and rider logo was moved forward so it is just above the rear of the trigger.
I have not encountered a 6.35mm Bayard that has the circular cut at the front base of the grip for removing the magazine, but my database for these guns is limited. The magazine is the same size as those for the 7.65mm and .380 (9mm) cartridges, but is stepped near the top and indented at the rear to fit the smaller cartridge. There is no fingernail slot at the foot of the magazine. The magazine holds 6 cartridges and has four holes in each side for viewing cartridges. It is marked with the caliber designation.
The 6.35mm gun is marked on the left side of the slide in all capital serife characters as follows:
☼ CAL. 6.35 MODELE DEPOSE ☼
All other markings are identical with the earlier guns, with the exception that the left side frame markings have been moved to the rear as described above.
The NRA Book of Small Arms, by W.H.B. Smith, says: “This Bayard is one of the smallest pistols ever built for its cartridge and suffers from heavy recoil. It is not a particularly sturdy weapon.” He says pretty much the opposite about the .25 version, stating that the gun is an “excellent Belgian variation of the Browning,” and also: “The Bayard 1908 is of original design. ... It is an exceptionally sturdy weapon of its class.” In the entry for the .380 caliber Bayard, Smith says: “The Bayard is produced by one of the best European manufacturers, the Anciens Etablissements Pieper at Herstal, Belgium. ... The weapon is noteworthy as being the smallest, most compact, and lightest .380 caliber automatic pistol ever built.”
