Cases for S-100 Guild or S-73 Dearmond?

Will these guitars fit in Gibson or SG cases? Checking out a Gator case, formed but not hardshell, for SGs, wondering if my S-73 will fit.

Thanks.

I bought an Epiphone SG case for mine, and It fits the ones made 1975 and forward. I've not tried to fit one of the reissues in the SG case, but the late 70s ones fit marginally well in the reissue case. I'd be careful.
