They look well made, despite the somewhat fuzzy soft contrasted pictures. The grille treatment is unique AFAIK, never seen that before, but tends to suggest something in the early 60's. The kicker is the very deep dimensions of the cabinet, very unusual. Is there any picture of the back showing connections and with the grille removed? Any idea of dimensions because for a 10" and mid/tweeter, cabinet looks very large volume for something like that.
The veneers are bookmatched so that's a nice touch. I wouldn't be surprised if this was a very nice DIY effort. For $35 and 35 miles of driving, I'd pick them up. Even if the drivers were run of the mill, the cabinets could easily be repurposed with a new baffle, appropriate drivers, crossovers, and box design. Could even make for a decent Woofer box with separate horn and driver on top, a la Econowave.
