Mid Century Nesting Tables

Thrift shop find today.. They look to be mid century construction, not sure about the design.. The makers mark is worn but looks like a small circle with a 9 letter word ending in estor, with a big A in the middle..followed by the numbers 528 a big space and .0, but not sure. I am also embarrassed to say that I am having trouble identifying the wood..First thought was mahogany... But could be teak and walnut..all that being said, they are cool, and a bit larger than most sets... They will look good in my house!!
