It would fit me.
But, it looks like someone took a rasp to the nose comb of the stock. I would not say that comb treatment is typical Purdey.

When I was in their shop, they were still emulating Ezra Hand's work.

Something looks funky there.

For me, 2 barrels, dt, ej, sg, sf, deeley latch, 1 1/2 x 2 1/4, and 1/4 and 3/4. 24lpi or less, POW with cap a close second.
Perhaps not the most efficient, but always makes me happiest.

Out there doing it best I can.
