Help on a Burner

[AndreAlmeida]

Hello Ken,

I'm currently in a pursue of '92 5 string burner, but i have a little doubt on the serial number which is 92824CR5.
I know that "92" is year of make, "824" is the number of burners made at that time, "C" for custom and "5" for five string. However, i don't know what the "R" means, maybe it's a type of wood i'm not aware of... The bass has a translucid high gloss red finish and the wood below seems to be quilted maple, but i'm 100% sure...

Thanks for the help!
