Alps or no? (clones/skcl/skcm?)

[roselios]

Hi can you help me with the definition of keyboards I think it's alps skcl from the salesman I asked for pictures and he will send them soon.
And also I think that the photo itself was not bright, etc. and because of this, I think that it is very rare skcm lime, and also there is a blue stem, please help friends, already studying 3 months vintage scrolls and hell I like it.
I wrote through a translator, since I am Russian )

That's an ntc6251 on the left with alps clones. Here's the wiki page: wiki/NTC_KB-6251#KB-6752EA

And on the right is some dome with slider keyboard, don't really remember the name, but I'm sure it's not alps.

UPD: it's this thing wiki/Oriental_Tech_OK-100_series on the left

Do you think to take clones or not, they are very cheap 1-2 bucks
