Photographic record

3 photographs

Side view of a dark Ahrex FW503 size 12 hook on blue grid paper, with a closed ring eye at the right, a plain shank, a rounded bend at the left and a barbless point.
IMG-1Ahrex — New entry — image 1 Ahrex FW503, size 12, side view. Closed ring eye turned down, plain shank, rounded bend, barbless point, glossy dark finish (P).

How to identify it

Identify the packet by the model code FW503, the words DRY FLY LIGHT BARBLESS under FRESHWATER SERIES, and the white AHREX wordmark on a blue band P. The back carries the warning that the hooks are extremely sharp in Danish, English, French and German P.

No stamp or marking is visible on the shank in the side view P. A loose hook would be hard to attribute to the FW503 without its packet I.
