That is the style number and probably the order number !! That would mean your table was made probably 1940`s or 50`s !! Looks like good quality and made of mahogany !! You can usually find this type table in the $150. to $200. range !! Could be slightly more or less depending on size !! These are usually an easy sell since they can be used in smaller kitchens or dining areas !!
No way to know who made yours since so many mfrs made similar ones !!
Scroll down on the link and you can see three examples !!
