Are all Morrison's FF compatible?

[Rick Butler]

I have an older Morrison Recurve I bought on the big auction site a number of years ago.  It's not marked Cheyenne just "Morrison T.D." Limbs are honey stained 'boo and the tips are what appears to be micartca.  It came with what I believe is a B-50 string.  Want to try a FF but not sure if it's compatible.

All of the Morrison bows that I have seen are FF compatible but I would email Bob Morrison to be sure.
