I guess this might be repairable by filing down that blob?
Oh yes - got rid of the (white) gold, then the nickel.
What remains is another 200 or so micron fill of a Pewter like soft white metal, but under this is the Brass case - but made of separate blocks.
I think the case is made of 5 Brass parts, placed in a mould then this soft white metal poured in to create the entire case.
Repairs have been attempted using lead, silver, brass etc but to no avail.
Filing the blob just started peeling the fill from the brass.
No-Go.
