A genetic test would be the only surefire way but I'm sure that's cost prohibitive. The scratch and sniff test could work but that's subjective to some degree.
I've been following Hoboken/early Westerly D-50s closely for a few years now. In my opinon, they are some of the coolest Guilds ever. The only thing I haven't done is started a database to track serial numbers and save pictures. I've said this in the past here, but I think there are much fewer Brazilian D-50s than is generally assumed. For whatever reason, all the 1967 D-50s I've seen appear to have Indian rosewood backs.
Here are a few examples:
AL-464 with Indian rosewood back and Brazilian sides (http://jimadams.info/Photos/67D50.html)
Another at Gryphon with Indian rosewood back and sides (http://www.gryphonstrings.com/instpix/38800/)
