Appalone Rudkins is quite a name, I'm surprised I forgot it. Many thanks again Jim.
I also read the Mount Vernon declaration regarding the blades coming from Solingen and was convinced they simply accepted it, due to the preponderance of blades from there and the relatively low profile of Oley. Of course, Oley was a Solingen man, so the market would have been told it was made by a Solingen smith.
What cannot be ignored is the fact that colichemarde blades were machine rolled, and Shotley Bridge was the only place with that machine.
History is peppered with declarations about the Shotley Bridge enterprise existing to fashion hollow blades more efficiently using a secret machine.
There were two machines of course- one being simply (also much mentioned) small ultra-hard dry grinding wheels which Angerstein sketched for us during his visit to SB (in 1753). He also stated that Oley was concentrating on hollow blade smallswords and a lot of etching was being done in the village (by Wilsons).
The groove in colichemardes is way too accurate and uniform to be worthwhile fashioning by hand. I've looked at a lot of those blades, and also non colichemarde blades with that groove (such as my William Kinman) and it is quite obviously machine made.
As I've stated before, all hollow blade colichemardes are machine rolled, ergo all colichemardes are from SB.
No-one has been able to tell me when and where hollow bladed colichemardes originated, or explained why they appear to only be hilted in England. I am happy to hear any declarations of such. This is a completely new issue that no-one has - till now - explored; it should have been!
