Thank you gents for your replies, all food for thought, and wanted to update in case anyone’s interested.
The ref’ to piano tools was interesting, after a bit of searching, I finally came across online info here
J. & J. Goddard | Martin Shepherd Piano Service
with the following small ref to W. Baker
‘Piano tools made by W. Baker, London. William Baker appeared in the 1881 UK census, listed as a tool maker born c 1837, in London. Not sure if this is an older relative of G. F. Baker.’
So another obscure London toolmaker that I was not aware of previously, and likely to be making tools for more than one trade ? So, possible these were piano tools, or some other trade. Looking at the fonts on the tools, they are identical types so can be reasonably certain its the same W Baker.
The points ref’ to shipbuilding and rope could be also be very relevant with the Thames in London?
I guess as these all came from a carpenters tool chest, they were likely were re-purposed for a different task, all good thoughts provided, drawbore pins a good call also. If only tools could talk and clear up their mystery.
I have not come across a brace with missing jaws yet, but maybe in another chest I’ve yet to explore. Thanks Geoff for the link, very useful.
Thanks all for your thoughts
