I found the
Weber Plates online years ago, but I can't remember where. Maybe Virginia University. They were ok scans of the original plates, I think. I have dial-up internet access but will try to load the entire Plate 166 as well as just coin numbers 4576 (possibly your target coin), and 4577.
In the
Weber text for these coins, it is said that coin number 4576 (strung bow/arrow
head) is "under 4577" in the plates, while the coin number 4577 (
Athena head/owl on
amphora) is "under 4576" in the plates. Apparently the images for these coins were incorrectly numbered on Plate 166.
Both coins are listed as issues of Polyrhenium in the
Weber text.
