I recently acquired this Dog Nose fork from an English auction house. They said it was by Dike Impey c.1725. It only has part of a maker's mark with no trace or evidence of any other marks. It measures about 7.3" long. It is kinda late for a wavy end fork but not unheard of if he was rounding out an older set. I suppose it is also possible he made this while unregistered or that it is not the mark of Impey at all. I only have Grimwades first edition so I am not sure if there is any updated info on him in the later editions. I also would love to know who the crest belongs to.
