Hi,

I have found again some strange keyboard, probably from typewriter, some electronic type.
I has, I think, mechanical switches. With cross stem, fitting Cherry MX again. But without any marks.
Keycaps are from thick ABS, some has adaptor to hold at the switches.
Some keycaps are doubleshotted.

On the three mechanical pulling switches, for paper, I think, there is a sign Futaba.

Thanks for help with identifying.
Btw. I am going to sell this nice KB, probably.

I have found some similar style - Smith Corona, but it isn't the same

I think they are a variant of wiki/Futaba_MD_series

Hey buddy, I found an old calculator with the same switches and same type of keycaps.

The keycaps will not work on MX switches because the stem is too thick in radius and can't go down together with the stem inside the switch :)

White circle is the keycap stem :

Hi, thanks for update. I tried it with some caps from old Chicony with MX blue switches and I think, I managed to put it on :-)
But I did not take care too much, I just thought it was compatible :-)

Pretty sure they're wiki/Mitsumi_standard_mechanical, as I also have a typewriter with those switches. I can confirm that Cherry MX keycaps will not fit and vice-versa. I can also say that Mitsumi Standard Mechanical switches are pretty nice.

I've had keyboards with switches from multiple manufacturers, so I wouldn't have a problem with some switches -- especially as they function completely differently from the alphanumeric block -- made by someone else.
