The 15" version of the dovetail plate is suited for the 130 f8 StarFire EDT, 155 f7 StarFire EDFS, ARO Maksutovs, Takahashi scopes and other instruments of similar size. The knob assembly features a brass pin with a tapered end to hold your sliding bar firmly without marring the aluminum.
I have two sets of these. No hardware is included, just the dovetail plate and sliding bar. Both of these are "slightly used" in excellent condition. Price from AP is $140 each, I'll sell these for $110 each shipped 2nd day air or both for $200 also shipped 2nd day air. PayPal accepted, cashier check or money order. Email me with question. Carl
