Hello Everyone,
My question has been answered since a new clip came up online, clearly indication that the pallets are plated in 24 carat gold. I am so happy because I personally own 1 of these in mint condition but with No.7 pallets not No5. Anyone interested here is the clip with the testing of the pallets.
