For sale is a flat foot Naiad crown as found on a 2915. The measurements are 7.75mm x 3.8mm and the tap is 10 or 1mm. I can’t find one that has sold so I’m finding it difficult to price but let’s try £750 ONO including UK postage with international shipping at cost. I have sold a couple of things here on OF so have some references available. Please let me know if I’m out on price. I have quite a few crowns I’ll be listing including another 3 flat foot ones
