My new-to-me 820s

Another 820 on ebay, this time a single 820C: Altec Lansing 820C Speaker System - Finest Speaker System From Altec - Original | eBay

Someone applied Formica to the cabinet, and painted the grille frame black. Also added the recessed round terminal strip on the back. (Normally, I think the wiring is simply supposed to be inelegantly routed under the cabinet. On mine, my uncle put a couple of brass binding posts on a rear side panel of each one. I seem to recall him telling me about it when he did it.)

His comment about "The cabinet has an original Altec Lansing spec sheet which dated this to early (2-31-1955). We all know there is no Feb 31 in any year. So this must be a rare error dating it such. The only one in the world!" is also present on the schematic in my 1957 820. Check out my photo in post #10 of this thread. Both my 1957 820C and his are "Issue 3" 820Cs.

GM: Note that his woofers have "20409" stamped on the cones - like the ones in my "Issue 1" 1955 cabinet. Though mine are painted gray, and his are green.

Once again, this cabinet has *both* the "holes" and the tilted triangular piece at the bottom. I looked really closely at my 1955 cabinet - and could find no sign of the tilted piece having ever been there. Nor does my 1957 cabinet have the holes.

His BIN price is $2995, but no one has jumped on it. Since someone just paid $7700 for a pair of these guys, I am guessing it is because of the Formica and associated cosmetic changes?
