Beeman Does anyone know when Beeman began including Picatinny top & bottom rail adapters for the P1?

I recently purchased a new Beeman P1 .22 cal and was surprised to see it comes with a Picatinny rail mount on the bottom and an accessory adapter for Picatinny for the top. The adapter is specifically made to fit the new dovetail indentations they've added.

Does anyone know when Beeman began selling these?

Emailed them but haven't received a response yet.

Bottom rail, 1913 Picatinny:

Top rail (built-in to the frame), 11mm dovetail with indentations & screw holes for the adapter:
