It is a test set, but adapted to a shorter riser. So a 60" bow instead of 62/64.
A side note, I ruined a limb by not taking enough care I guess in filing nock grooves. Split a 1/8"x 3" pc of glass off the edge by a nock while checking weight ...
Guess there's a first time for everything...
So new limbs gonna happen now... Not sure I have enough scrap to make em…
