help with cool retro logo hand drawing!

Hi everybody,

I was referred to this site from a "font fan". I know this is a hand drawing, but maybe someone out there knows something! This vintage hand drawn RCA logo is the inspiration for our album cover. if anyone knows a similar font i can use to get close, I'll add the lightning bolt with our graphic artist. our name is
" ristband " so the "R" and "A" need to be pretty exact.
