Here is one from Boyds.
And this is what they have to say.
CUSTOM DUPLICATING
[align=left]
Can’t find your model of gun in our listing? No worries! BOYDS’ is now offering custom duplicating to aid you. If you have a workable stock/forend we can quote you a price. All parts will be semi-inlet requiring fitting and finish. But it sure beats inletting your own from scratch! So give our sales staff a call for pricing and any other information you might need, we will be happy to help you anyway we can.[/align]
