Hi RDGAC,
with regards the pitting on the blade that is devoid of active rust...IMHO the blade has probably been subjected to electrolytic rust removal or the use of a weak acid.
Kind Regards David
PS With regards galvanised blades ....I believe Mole patented a galvanised blade or the process of galvanising a blade, in 1860 ......"galvanized,that is to say, coated them with zinc, whereby the said machetes and cutlasses are preserved from oxidisation" . However I think this was mainly for Maritime swords ...which were often painted (black) to help preserve them in the 'sea air'.
