Wanted: Model 12 Standard Trap Shotgun Extension Forestock|Winchester Swap Meet|Forum|Winchester Collector

I am looking for the extension forestock for a 12 gauge Model 12  Standard Trap.  I want the “simpler” checkered version, not the fairly extravegent version such as for pigeon grades.  I would like to get close to matching the wood in my butt stock, which shows up in the attached picture.  Also attached is what I think the checkering should look like, on an example of an extension forestock.

Regards,

Ordie
