On magazine v clip, I suspect the manual for the M69 Romanian Army Training Rifle referred to the cartridge feed device as a magazine (in Romanian).
Marlin Firearms sold the detachable box magazine for their Model 25 .22 sporting rifle labeled as "Clip".
For military firearms, like my M1 Carbine, ammo is fed from a magazine, and I have stripper clips with spoons for charging the magazines with cartridges.
I have a Carcano that uses enbloc clips that insert completely into the fixed magazine; the clip serves as the feedlips of the magazine.
Back in the 1950s when I was introduced to firearms, IF the only cartridge feed device ever used with a particular rifle or handgun was a detachable box magazine, e.g. Marlin Model 25, and the firearm was never issued with both magazines and clips, the feed device was usually called a clip. One syllable.
If I was calling in an air drop of ammunition, specifying "in clips" when the desperate need was really in preloaded magazines, that would be a big deal. Otherwise, meh.
I bought a M69 with a Taiwan made magazine from a table load at a gunshow for $60. Spare magazines were a sticker price shock. I took the magazine for my M69 and a spare clip for a J22 pistol, built up a hard solder lump on the J22 clip front and filed it to match the M69 magazine seating stud.
The raised rail in the M69 receiver is square cut, resembles a Weaver tip-off 3/8" dovetail scope mount rail, but isn't. I decided it was more robust as an iron sight rifle anyway.
