This is a sticker sheet for the Taito Egret 3 which has various labels such as those found on the PSU. It shares the part number with the Sammy Atomiswave SD, as the same sticker sheet is used on both machines.
A great item for use during a restoration project for the purist who likes everything to be just so. Genuine Taito item.
Please note: The top item in the photograph is the description label that came with these labels from Taito, and is not included.
