I thought they used SMK alps mount switches ("monterey" blue.) or Hua-jie (white), and not white alps.
Note the actual model number is 1946 as the 1903 model has a DIN connector, I believe. Eitehr way, I note that both are printed on the back.
Honestly, I was expecting NCbound10 to price these higher, especially as the last minitouch on eBay went for like $70 (a few days ago).
