Shaper Info...Mid 60's Petrillo Minigun

I just picked up a mid to late 60’s Petrillo 8’8" Minigun with a glassed in red skeg…Looking for any info I can find that would narrow down who outside of Frank Petrillo himself might have shaped it. I’ve found thru researching the Petrillo history that Velzy, Robert August and Wayne Brown were shapers there during the 60’s but the board is unsigned.

Could be a Jim Glanzer shape.

Primer, do you know if Jim Glanzer is still around?

Some where in South Texas.
