Somebody got any pictures of those?
I think there´s even cf-100 a.k.a

Yeah this topic needs pictures.  
Nothing in my boombox database under the brand Mark.

Calling GusG about the conion a.k.a!!

I´ll start!

 This one was also sold as "Mark".

I have one somewhere. Full of oil and grime.

So which ones they rebadged?

the top one was also a NIPPON an international....my friend had the Nippon in gold back in the day...the bottom one...hmmmm the Mark brand at the bottom looks like someone wrote that on themselves?

I have one sweet Mark... 

Mark was sold in scandinavia and yes, there was an c-100 aka brandet MARK. mark 4647 or something I think. I was about to by one that was advertised on a site a few yers ago, but the seller changed his mind :/. I also found one a few years later, a guy that was bying random 80s stuff from me for a movie had one, but he didn`t wanna sell it. So there are still a few out there, even thogh they are rare as hell...

Anyway, the brand might still exist, at least it did just a couple of years ago.
