Even though Belgian "Army" literature may indicate "M1924, this is incorrect. The FN M1924 rifle had an intermediate length receiver and bolt ( as in the FN inspired Yugoslav M24, M24/47 and M48 series of rifles.)
In 1930, FN made a "Normal length " Mauser action, as in the Gew/Kar 98 receiver dimenstions ("Standard Length") and the "Model 1924" was discontinued by the mid 1930s.
IN 1948-50, improvements to Machining the receiver led to the production of the "double broached Bolt ways" receiver, for all Post-WW II "M1930s" These have been known thru collectors circles as either "M1930/50, or simply M1950".
The "M1950" design was produced initially in 7,9mm for the Dutch and the Israeli Defence Forces ( 1948-50)--- and then for Colombia (1950) Morocco as the Gendarmerie Carbine ( 1950-60) and the Belgian Army and Navy ("ABL"); the Duchy of Luxembourg ("AL"); and the Belgian Congo Force Publique ("FP"). These Latter rifles were all factory made in .30/06.
NO other calibres were made, although a special batch of these actions in 1952 were set up as Target Rifles for Venezuela for the Pan-American Rifle Comps, in 7mm Mauser ( 26 inch barrels, and Windage adjustable rear sights...only a few 100s prepared.
Last of the Regular Factory produced "Mausers"...unless one counts the ZCZ (Zastava, Kragujevac) "M63 "Tanker" Commercial Model for both Euro sales and a certain US distributor of "Humped and Bubbaed" Mausers. The "M63" is based on the M24 Intermediate action...a nice fake, but still a fake.
