Robert's Brothers Glass and slate call

[Ithaca 37]

I just saw a Roberts Brothers call a buddy got and I was pretty impressed with it. Do any of you have experience with one of them?

Hi Ithaca 37,I bought one myself a couple of weeks ago.It's a great sounding call,i don't
care much for the striker it comes with but
i'll figure that out later.Good Luck
