Question about 50th Anniversary Bear TD riser

[Orion]

Is the throat area, and perhaps the entire grip of the 50th anniversary model, larger than the other recent incarnations of the A riser, say those made the past 5 years, including the Legacy model?  Any other differences? Is the 50th anniversary model supposed to replicate/duplicate the risers made in 69-71?

Looks like the materials used in the 50th Anniversary model (bubinga and phenolic or dyed maple) are the same as in other risers currently being made.  Can anyone confirm or disconfirm this?
