I would agree with Michelle. That is not a 1407. A 1407 stock was made to comply with UIT Standard Rifle rules which prohibited adjustable cheekpieces, thumbhole grips, and butt adjustment during a match.
What you have is a 1610/1609 or early 1810/1809stock. It was a no-frills version of the 1613/1813 Supermatch that offered the same degree of butt adjustment, but was made of beechwood not walnut, and was sold without a palmrest. The very deep fore-end compensated for the latter. There was a 1410 stock made in the 1970s, but those had a hole in the stock by the bolt slot to access the trigger adjustments, so it must be for a 16 or 18 series rifle.
When sold with a heavy barrel it was a xx10, and became a xx09 with the lighter xx07 barrel.
It's worth more than a 1407.
