Kurt - Thanks for sending the Potter & Macquarrie ink stamped target arrow. As you can see in the photograph below, the same ink stamp pattern but slightly larger size was used on this rawhide backed bow. I've had this bow for a number of years, it is in excellent condition and has unique metal horn-nocks.
Their combined and shortened name, POMAC, is branded into many of the arrows they sold and used. The branded arrow at the bottom of the photograph, is a real treasure as it is inscribed just in front of fletching "MACQUARRIE NAA 1948 RENO" and was found with a very Rare 94 Large Barbed Tubing Ferr POMAC Broadhead that is shown on page P-14-3 of "Broadheads 1871-1971 Identification and Rarity Guide, Second Edition".
What can I send back to you for the neat little ink stamped arrow ?
