Where is the casting or OEM part number (X109BT-25 / TL-B150-25 / 1001B-3X1/2) stamped on this part?

On Trim-Lok OEM assemblies, look for the stamped or die-cast numbers (X109BT-25, TL-B150-25, 1001B-3X1/2, NUCAMP-GALLEY-SEAL) on the underside of the metal housing, along the link arm, on the stainless hinge track, or printed on the circuit board/valve label.
