I vote for the G&H treatment, perhaps hollowed out and a walnut filler added?

As an aside, has anyone here done (or seen one done) a conversion built on a Model 15 BSA Martini? The rear sight dovetail incorporated into the rear of the receiver would be a stumbling block in the quest to make an elegant arm out of it, to my way of thinking. (Or perhaps incorporating the original P-H sight into the final design?) I have one of these that I've been casting a covetous eye on in regards to a sporter similar to the one taking shape on this thread.
