Of course, segmented shells are a different proposition - no mould required. So long as they followed the same process, with the same materials, & the same attention to detail, they'd have a Guru - it's a recipe, a material quality selection, & a process.I'm surprised to hear you say this Andy. What if DW bought Guru, did their own shells, then put the Guru name on it? Surely they would be different, even if esthetically the same. If not, why spend so much time on just the shell?
Same applies to replicating Slingerland shells. So long as the process is the same, or equates to the same result, the origin of the moulds is irrelevant outside of legacy marketing equity. The process and the materials are way more influential than the moulds themselves.
