a question about stock car classes

[NW Mailing List]

In digging through files and pictures, I have found evidence of N&W stock cars in classes SD, SF, SH, and SK.   The gaps cause me to question were there any SG, SI or SJ class cars as well?  Or, were these letter designations just indicative of the class of boxcar that these stock cars were created from?

Thanks,
Brent
