Model Number and Tag ID Question

[MikeBatalon]

I recently purchased a Seymour Duncan pickup from GuitarElectronic.com and I am uncertain as to having received the product I ordered.

My desired item is the Classic Stack Plus STK-S4m. It came in an open box with model #STK-S4m BLK though the pickup is white as I requested. The sticker on the bottom of the pickup designates it as only STK-S4.

My question: Does the RW/RP Classic Stack Plus middle pickup have STK-S4m model number on the sticker on the pickup?

Thanks in advance for your help!
