OK! Who's up for A.) a mystery and B.) giving build advice?
So quite some time ago I had a good friend up north nab a Sunn 2000s head (which got the spa treatment from Nate) and mentioned it here. What I haven't mentioned is that it also came with a massive 4x12 cabinet. it was so big I could not bring it home with me on that trip, but because of being up north hauling gear w/ a borrowed truck, I was able to wrap it in a tarp and bring it back "Below the Bridge" (a common regional phrase) this past weekend.
As it turns out, it's a
really nice-sounding cabinet! Loaded with Altec 417B speakers in fact. Both Nonagon and Maple Stave played through it at Thundersnow on guitar but I'll say it really shined when Body Futures used it for bass.
So first the mystery...any ideas what this thing is? It might be a home-brew but if so, it's one of the most professional-looking I've ever seen, especially with the torlex and piping around the grill. It seems well-designed, well-built, and solid. It shares some commonalities with some of the earlier Sunn cabs I've seen (middle port and ONE MILLION screws holding the backplate in) but the tolex and the corners are wrong and lots of research I've done just doesn't show any Sunn builds that line up w/ this. (Please note it's upside down in the photos so I could work on getting feet or casters installed but more on that in a sec....)

Second is a question. So this thing is barely mobile, especially without handles or casters. I was going to screw some casters on...but whenever the old ones came out it took a pretty good chonk of the plywood with it. Wondering what the most solid way to deal with this is? Cut out the hole and glue in a piece to fit? Honestly wondered if it would be easiest to fill it with epoxy. Overall those sections still seem like they have a good 1/2" of plywood left even on the worst gouge shown here with pen shown for reference:
Was thinking about edge casters but I don't think I can get away with it on normal rear back side due to the back panel access. Was thinking around on the side? but I think it might be too massive for that & would flip around wildly especially if it's going up/down stairs.
