purchased an antique chess set and table, looking for info

I've been going to the Brimfield flea market for years and I recently started getting into chess a couple of months ago so this year I had my eye out for any neat chess sets and so I bought an old isle of lewis chess set and a new chess table. the story the seller gave me was that the set was aquired from an estate sale of some sort(?) someone had passed away and these were taken from the home, other than that I really don't know anything about either. I'm hoping to find out information about the history of each item and additionally what would be the most appropriate method of cleaning each item.

I haven't been able to find anything on the set, I'm hoping to find maker's marks of some sort and any information about where to look for that what be greatly appreciated. They seem to be made of some very heavy plastic? we thought maybe Bakelite but were uncertain.

When researching the board/table a saw a few tables with the exact same top sold for 30 times what I paid for this one which leaves me cautiously optimistic about the value but also worried because I would very much like to just clean this one up and use it as a chess table but now I feel like need to know exactly how to clean it because I don't want to damage anything. the seller told us it was copper, we thought it looked like brass but now I can see copper red showing through in some areas.

The only makers mark I've been able to find on anything is what might be a signature on the middle of the under half of the table but I can't make it out, information on that would also be greatly appreciated.

EDIT: Also the set is missing a white pawn as you can tell from the pictures, but I'm figuring I can just by a replacement piece with the same weight. or even just make a new one from wood or something.

Sorry but I can't help with any info but I just wanted to say that I really like your table, great find. Congrats. If I were lucky enough to own it I'd try find a set that matches or comes close to matching the pieces that make up the patterns surrounding the playing field.

The pieces are a reproduction Lewis set, they are fairly common and available from a lot of sources in different sizes.   The table appears to be embossed metal, here is an example of the top on a different table, frankly I think yours looks much more original/plausible than the one in this auction: https://www.1stdibs.com/furniture/tables/game-tables/arts-crafts-chess-table-drinks-cabinet-embossed-brass-chess-pieces/id-f_15852091/ Here is another http://www.chessantique.com/chess/chess_pages/boards/AustroHungarianBrassChessTable.htm  and another https://www.richardgardnerantiques.co.uk/shop/sold/rare-antique-french-chess-table-and-chess-set/ (the description on that one is quite plausible).  And I have just found the people who make them: https://www.taylorsclassics.com/products/table-tops/indoor-table-tops/brass-table-tops/ so all those auctions talking about the 19th century are probably just perpetuating the usual behaviour of the antique industry.  

Thank you! additionally, how would you suggest I go about cleaning the table and pieces? the table is just dirty from being however old it is, or being stored where ever it was. And the pieces aren't sticky per se, but you can sort of feel the years on them when you hold them haha.

Thanks! I absolutely love the table, online I've seen a few French sets that match the engravings which makes sense since it seems like the table is at least based off of the tables that came out of french chess clubs in the early 20th century.

For the table, the wooden part looks pretty filthy, it will probably respond well to waxing and polishing with a (non-silicone, non-synthetic so it can be gotten off later if you need to) cabinetmaker's wax.   You could try some spray furniture polish but thats not so good for dirt.  Apply the wax with very fine steel wool (that avoids clumping to some degree and scrubs the surface, lifting dirt) , let it dry and buff it off.  What to do with the brass depends on how its finished.  Its likely to be lacquered and so it would wash (you can't polish lacquer).  The pieces are most likely to be resin so they will tolerate a quick wash (the dark bits will be painted).  I have seen these sets cast in plaster, which is both fragile and not water resistant, so check for white chips.  

@Greghunt that's some serious Antique Road Show type of research and knowledge you just dropped on this thread 👏.  @The_Newest_Addition I personally always found the Isle of Man sets to be a bit funny. The Queen looks like a mother who just came home from work and sees the mess the kids made in the house "Oye vey", lol.  Not in your set but in some Isle of Man sets the Bishops have these funny faces too while apparently biting their shield in terror. 

Kinetic, thank you.  I just did a bit of Googling.   The ones biting the shields are rooks in the form of berserkers, basically crazy vikingrs, its not terror, its a fighter wanting to get into battle as soon as possible (https://en.wikipedia.org/wiki/Berserker) .  I happen to be very fond of those Isle of Lewis sets, they are more human than other sets are, the Queens are part of that.   

I love this @greghunt guy, and that @efimlg47 too. They are forum wizards of sort, like B-52 bombers carpet dropping facts and research onto the masses. Tree ents of knowledge.

I will take close ups of all pieces and post them soon

I'm taking your advice on the wood part currently and will update when done

@Greghunt I like the Isle of Man set to. I just find it a little funny.   I'm also a bit of a history buff specifically military history so I'm familiar with Vikings and Beserkers but you've  once again educated me. I didn't know that that piece represented a Beserker. Very cool tidbit .

Huge, grumpy and wrinkly?  Yup... 

Here are two books I've read that really go in depth into the history (or suspected history) of the Isle of Lewis chess pieces. Interesting stuff if you want to learn more about them:

Put in washer with dish wash soap then dry it in oven
