Is this a correct service dial for a Speedmaster AML dial ?

The second one i see pop up recently, this one is one ebay from Swiss, but with a much thicker / fatter font then usual i think, and a different letter P.
Could be correct but the seller covered the back so it does not show SL or other markings which raised my suspicion . What do you think ?

There is no correct service dials for 321’s they are made in small batches and have variation.

for 861’s there are no service dials. Just current production.
