I'm posting this e-Bay listing of a similar guitar. Has the Kahler Traditional 2500 series trem and active EMG pickups. But it isn't a Flyer; the seller is mistaken. Probably an S-260, S-270 or S-271.
Body shape is more conventionally Strat-shaped, as opposed to the elongated lower treble bout on a Flyer. This shape, which is the same as the S-270 Runaway in my signature, fits in a typical guitar stand lots better than a Flyer does.
It's not my listing nor my recommendation, just a price check (not a bad deal) and some food for your thoughts. But in defense of the seller's misidentification, it's quite understandable. Hard to research these guitars, plus the S/N's of the S-260, S-270, etc. use the same S/N prefix and sequence as the Flyers.
Fortunately all mysteries will end when Hans publishes Part II of
The Guild Guitar Book.

Also, re: poplar or maple. At least generally speaking, when any of these guitars were built with the maple body option the finish is natural or transparent to show the wood figure.
