Wow !! Nice cabinet. If it's in your price range..... then I'd get it.
That is a superb example of a typical Mario Bros. that you will find most often.
BUT......
Just for the record, those were kits for the blue cabinets.
The original came in the widebody cabinets with the speaker in the center of the front panel and all that good stuff. (orange and black)
Note that the last three letters of the serial number are PAK, meaning it was a Nintendo PAK that was installed. (kit)
Also note the manual they have pictured. (from a kit also)
But with all that aside it's a very nice Mario Bros.
As original as it gets in that style cabinet.
