I've been doing a lot of table shopping these past couple years online and I've seen a few of those. They are really nice tables, but like 9-ball said tables aren't fetching decent prices these days as the market is flooded with them, not to mention many people have and still are needing to just dump them cheap because of loosing their homes or downsizing to smaller homes or apartments or whatever. I don't even want to tell you how cheap I've seen one of those sell for lately, it would break your heart and make you think it's not even worth moving or saving which it is, it is an antique for sure.
If you held on to that table and refinished it perfectly, and then the economy turned back around and things had the same value as they did before, and the glut of used tables finally dried up and demand for more tables came back you would be looking at what 9-ball said maybe 9k or so tops. But in the reality of todays economy and considering all the competition out there, and that this isn't really rare or anything I think even refinished you'd have a hard time getting 2.5k. Most of those era or similar tables that I've seen in my area that have actually been *selling* and didn't end up relisted forever sold for around 1k or less. The cheapest of which sold for less than it would cost to just have it moved.
If it were me, I'd take it apart and store it carefully somewhere until it had real value again, if you must take it apart and move it. And make a project of refinishing it in your spare time just as a future potential investment.
Right now it's value is at it's all time lowest, so why sell it if you don't have too...
It also wouldn't pay to have someone refinish it now just to sell it in this market when you'll have a hard time even selling it as is.
If you contact classicbilliards.net they can probably find you a manual for that or a similar table to see how it comes apart. I think the rails bolt from the sides, those trim bobbles probably hide some bolts which you may need a special tool for again from classicbilliards, then once you get the cloth off you have to dig out the filled screw holes in the slate to get to some more screws and just start taking it apart one screw at a time. It gets obvious once you're past the rails off and cloth off part, and get the screw holes uncovered. I have no idea if it's 1 2 or 3 piece slate but it will be very heavy that's for sure.
Those slates are drilled vertically from the top and also through the sides for the rails and you have to be careful handling them and working on them. Be sure not to overtighten anything if you are reassembling it later.
Once you see the bolts holding on the side rails you may be able to make your own tool up to take them apart, it'll be clear what you need to unscrew them once you see the bolts.
Here are what they look like restored, not really that different from that one at all. That's in really good shape other than the wear on the rail tops, which anyone could fix up as a diy project fairly easily if motivated enough. Wouldn't require a professional, or a lot of money, if you couldn't afford to invest in a pro to do it.
