Penn Delmar 285- worth anything
I've been collecting, servicing, and selling Penn conventionals for over 40 yrs. Currently have seven 285 Delmar's still in the box and can tell you they are only worth as much as someone is willing to pay.
Basically, they are quite common and not much more than an entry level general purpose reel. If a collector was desperately seeking a 285M (metal spool) mint in box (MIB), he may pay as much as $30-$35.
The rarer Delmar 286 (which has slightly more line capacity) which Penn made for a short time prior to moving their factory in 1940 sells for $35-$45 MIB. One of my pre WW-II 285's has an original price of $3.75 on the box.
