I wish there were only 5 carbine versions.
As I am an obsessive compulsive Dutch carbine collector (there is no cure), there are 17 or 18 variants of the Dutch M95 carbine out there.
I only have 10 so far and worst of all I know that in all probability I will never find the other 7 or 8.

Top - Old Model No 4 Wielers (cyclists) carbine
Bottom: No 3 New Model modified Genie (engineers) carbine. The bayonet is common to both carbines.

No 1 New Model Cavalry carbine. Near identical to the new model No 4 for the cyclist.
