Not modern stock dimensions. The Parkers are an unnecessarily complicated design. All should be glass bedded if using the original wood. When a picture of a blown up gun appears here, or, elsewhere, it strange how often they show early Fox guns.
Using old doubles as high volume shooters is a bit problematic, in my experience. Imagine using a 1948 Ford for daily transport, and you are on the right track. Lots of fun, but, keep it limited in use.
Best,
