Hi The "gray" case is the original design case. For what ever reason, it turned out to be a problem for at least one intended application. The final design case flipped the board over to take care of what ever problem the original orientation created.

This unit is backwards from the gold box T-Bolt. The circuit card is mounted on the non-flanged case half (that has the connector cutouts). There is no serial number sticker, but does have the power supply sticker next to the connector. And just for fun, the power connector is backwards from the gold box units. You can guess the next line... Does anyone need a T Bolt Aroma Therapy device? One scent (not pleasant), slightly used, real cheap. I was rearranging the bench and plugged a properly keyed power supply into the gray box. The power supply that I did have on this unit doesn't have the keying lock. Of course, this one has (had) the good DS1620 (D rev) chip. Oh well, live and learn.
