Need SB series Dial Parts

[Snowden, Douglas]

I am looking for parts for my SB-300 / 401 radios., Mostly I need the
plastic
parts, including circular disk that has the digits on it, as well as the
zero set
window.   No emergency, just want to make the radios look pretty.

Also, someone told me that the SB-401 tx should not use 6146B tubes in it
but
you should stick to the original 6146 tubes. Is this a fact?
