Doctor Who Keyboard
Total is about 244 keys.
The top is 25x5 = 125 keys.
The bottom part is about 93 keys, plus 4x6 = 24.
This appears to be National Grid keyboard used in UK.
Apparently, this keyboard is used as a interior prop in British TV scifi series Doctor Who's TARDIS (Time and Relative Dimension in Space). TARDIS is the name of a time travling machine that looks like a UK police box (public phone booth used for emergencies)
