Yours is the first Type II ejector iron I've seen where the "banjo" escutcheon features the two early wood screws in the escutcheon in addition to the machine screw. I've no idea why this was done, but I can also tell from your photo that yours is a transitional iron as the width of the strap at the base of the iron has not been widened (reinforced). Therefore, and based on the fact that the base width of the fore iron strap still remained unchanged when this gun was built, I can only assume that Hunter was still in the process of determining the final design for their Type II escutcheon. Use of this gun demonstrated that those two tiny wood screws were unnecessary; and were in fact a problem; as it is clear from the condition of the screw slots in your photo that someone was constantly cranking on them so they didn't fall out. If this were my gun I'd be tempted to find a later escutcheon as a replacement and keep the original as a souvenir. As to the shape of Type II fore iron escutcheons, one will see some occasional variation; but all the variations I've seen have been in Hunter's highest grades. In Brophy's book there is a photo of a Deluxe Grade having the most uniquely shaped Type II escutcheon I've seen; but such work is not common even among those highest grades, so I suspect that the escutcheons on such guns received this unique treatment based on specific customer request.
