GENERALLY:  This Chilean Comblain rifle is not a Belgium Comblian nor is it the expected Brazilian Comblain variety. For additional discussion of the Belgian and Brazilian models follow the foregoing links. Walter indicates that the standard Belgian version was exported to Greece and later Chile and Peru, and goes on to describe a distinct model made for Brazil. My information, however, indicates that at least the rifle profiled here was a distinct third pattern for Chile at least.
PHOTO: The rifle shown is a Chilean Comblain, model designation unknown, but carrying a prominent Chilean cartouche on the right buttstock.

DISTINGUISHING CHARACTERISTICS:  This rifle, like the Brazilian model, has a seperate lower tang, shorter, chunkier receiver and the rear sling swivel attached to a seperate plate which itself is attached to the lower front of the receiver. However, like the Belgian model but UNLIKE its Brazilian cousins, the Chilean Comblain has an exposed hammer with cocking spur and half-cock safety and mounts steel barrel bands, nosecap and buttplate.  However, like the Brazilians, this Chilean is also built on a steel receiver.  Chambering is unknown at this time.  
Notice the small part of the hammer spur jutting at an angle right below the rear part of the receiver behind the trigger assembly.  The Brazilian models, with their shrouded hammers, don't have such a hammer spur.   Also check the photos of the Chilean vs. the Belgian models.  The Chilean is much closer to the Brazilian variant.  See the photos of the Brazilian Carbine on the Brazil page.

MISC NOTES:  See also M1873 Brazilian Comblain (of 6 contract models) and M1870 & M1882 Belgian Comblain which are each distinctive variants.
