Help to ID a Vintage Montblac

Hi everyone, I am new to this forum. I was given this pen by an enthusiast but have no idea what it is or what it might be worth - any info you can give would be awesome!

Welcome home. Pull up a stump and set a spell.

Looks like a 420, entry level, steel nib, mid 1960s.

I don't see the line on the barrel that would indicate a piston. Is this a cartridge filler? If so it is probably a 1970s 221.
