Steve,
Thanks.
I thought it was but with my bad eyes I couldn't make out the stamp. You may know I'm queer for pre-war Marples and will buy them anytime I see one that looks in good shape. I like the London pattern Ash handles as well but they are hard to find. Big thing on both is how light and, there is that word again, balanced they feel in hand when meeting steel to wood.

BTW, in good shape means the back of the blade isn't pitted.
