know the brand of this Atari 800 keyboard?

[Ted Sandler]

I need to buy a new keyboard for my Atari 800 and I've been told that Mitsumi holds up better than Stackpole or Hi-Tek.

 

I am wondering if this keyboard is a Mitsumi:

I contacted the seller and he was not sure without opening the package.

 

Anyone have any idea what brand this keyboard is?

Thanks

Not sure but this is a stackpole.

Stackpoles don't use a mylar whereas Mitsumi do.

I see a yellow plunger on one keys.  Looks like a Stackpole.

Are Stackpole keyboards okay? I hear the plungers get brittle and break after this many years.

 

Also is mylar a good or bad thing?

 

Thanks!
