I concur with the view that the spoon is far more likely to have been made by Robert Goble the younger c.1720s. I say Robert Goble the younger because I have not seen evidence to assert that he is a son of the elder. He may in fact be a nephew, or even a cousin. Any thoughts on this point by anyone?
As regards restoration I cannot recommend anyone, Sorry.
Cecil C. Woods, in The Goldsmiths of Cork, published in The Journal of the Royal Society of Antiquaries of Ireland , Ser. 5, Vol. V, pp. 218-223, 1895, mentions: 1719, Robert Goble Jun, goldsmith, warden.
M.S.D. Westropp, in The Goldsmiths of Cork, published in the Journal of the Cork Historical & Archaeological Society, 1906, similarly mentions: 1719. Robert Goble, Jun, goldsmith, warden.
This to me suggests he was a son but I agree, it's not conclusive. As those venerable scholars of Cork silver refer to him as Jun, should we not do likewise? There may be evidence in M.S.D. Westropp's papers but I have no idea where there are kept.
