Did FN ever produce a commercial intermediate action?

There is some speculation regarding that. Obviously, FN made military contract intermediate actions between the World Wars, for the 7x57 cartridge.

In the late '40s, they began their popular line of commercial actions, which were standard length.

However, during the mid '60s, Heym made commercial mausers on what would appear to be an intermediate action that looks identical to the FN. They are marked EHM for Heym, and were imported into the US by Westernfield as the 720 and 724. Everyone swears they were made by FN, but they have a C-ring breech, which FN had long since abandoned. Their origin remains a mystery.

Z1R The first run of contract military Mauser system rifles for the 3 nations that combined to make what became Jugoslavia and which were marked CXC, for Serbia, Croatia, Slovenia in Cyrillic leters, used a so called safety breech system to include an extractor slot of about .050 depth in the breech face of the barrel. Serbia made pre 98 Mausers and had a ctg. plant which made what is called balloon head brass. Anticipating a re-order, FN allegedly made extra receivers. Jugoslavia expanded with the addition of more countries and was producing its own rifles, so the special and different parts for the intermediates held in reserve for parts was no longer needed. The first experimental commercials seemed to have been made from these parts. The only one I remember was carted around by the Stoeger Representative after WW-II, mostly to counter assertions eminating from Firearms International salesmen about who was first to handle FN sporting mauser type rifles. This one was in 7.65. The barrel contour was same as military up just past where the rear sight sleeve would have been, then it tapered to eliminate the step at the straight muzzle section. I suspect that this rifle was a bring-back from WW-II, and may have belonged to a Jugoslav nabob, who hunted and wanted a sporting rifle on an action like their own military. If it was true that in the kingdom you could not own a rifle in the military caliber then this might explain why this one was 7.65 mauser. The FN initial logo was rolled over the top of the receiver ring where the coat of arms would have been on a military.
