Hi Mike, I've had responses that indicate that Melville used a variety of methods to attach gnomons, from leading them in, fitting them with "flanges" underneath to the twisted tenons that you mentioned. No 2BA screws, though! So I am convinced that the ones on the Dunmore (Ireland) dial are replacements. If you have a picture of the actual shape of an authentic Melville gnomon, that would be useful - thanks for offering. (I have the one of the Salisbury dial that Nick Nicholls published in 1995). Otherwise, we will just re-fit the existing replacements which are acually quite reasonable.
