I'll offer my "Hardy Clone" by Berkeley made in Japan in the 1970's. This one is branded "Berkeley 530". Measures:
Outside frame 2-7/8" x 1"
Spool 2-1/2" x 3/4"
Double pawl. Excellent condition for one of these. My photos show it next to a standard 3-1/2" diameter model. (backing is included but not the line)
$80 shipped, $70 local pickup near Mill Creek.
