Thanks.

Re: Concentration levels
Hola Claudio,
General guidelines for Nickel Sulfamate bath concentrations are given on wikipedia. The page suggests a Boric acid concentration of 30-45 g/L, but the Nickel Sulfamate concentration would be ten times that amount (300=450 g/L), and, if used (?), Nickel Chloride would be no more than 30 g/L. These numbers are corroborated here: https://nickelinstitute.org/media/1759/platingandelectroforming_essentialindustriesfortodayandthefuture_10088_.pdf.
A nice treatise on electroforming metals, including Nickel, is given in this .pdf from U. S. Army Missile Command (1964): https://apps.dtic.mil/sti/tr/pdf/AD0464680.pdf.
Papers written by (the late) K. R. Smith may be of particular benefit for record stamper manufacture.
