TR,
I'll dig out a box of WRA stocks in the morning and post some pictures of what I call a Early Type III, Late Type III and Type IV. None of which would be in the Pot Belly family.

The long barrel channel posted about on my 5,8 has no M2 cut.

Thx,

P.S. Dave HH, has set the cartouche bar pretty high........ so don't expect anything like that baby!
