I happened to find a large (19") Mae Timberlake signed Hunter Arms trophy vase. I believe it could be a Roseville (Rozane Royal pattern) or possibly a Weller (Rookwood is also sometimes mentioned when discussing non-Lenox Hunter Arms vases).
I understand that Mae Timberlake did work for both Roseville and Weller at the beginning of the 1900's. Unfortunately the vase does not have a maker's mark (also I have never seen the Hunter Arms inscription with a date, shooters name or event/location).
I have pictured this vase next to a Lenox "River Dog Design" vase for size comparison.
If anyone has more history or information on this particular type of vase (or any others) I would be very interested to hear about it.
