Anybody ever heard of the "Woodside"??
...or the "Pelham" ??
Hi Mr. Smith. This is pure speculation, but I have ran into this with the Suc crystals also. In one instance I found a Westfield by the model name listed on the Bulova crystal package. So I think that since Westfield was owned by Bulova, Suc just labeled all the crystals for the Bulova company as Bulova and then the model name might be for a Bulova or a Westfield. That's the best explanation I have been able to come up with since the Suc catalogs don't list Westfield crystals seperately. Someone else might know for sure.

Original discussion with examples in above link, more than one example makes this idea hard to ignore.
