Casio 121

I am resident in the UK and have an old Casio 121 4 function mains powered machine with 12 nixie tubes circa 1967. The 2nd digit does not illuminate although the machine appears to be performing its arithmetic functions correctly. I have no manual for this machine and would like to repair it, they are very rare here. Any ideas anyone? Do you know of any uk resources I might try, and do you know where I might get a manual??? Thanks, Tim
