Unidentified AE20 horse and trident.

[Connect4]

This rather poor specimen has proved difficult to identify. 

It is similar to Mylasa types with a horse prancing and an ornate trident with the reversed S embellishments. However, these seem to be much smaller.

Obv. Horse prancing right. Rev. Ornate trident set above a bipennis.  S and reversed S embellishments above and below.
 
19.5 – 20.5mm, 5.3gr & 12hr axis

Any suggestions would be appreciated.
Thanks

Such a denomination from Mylasa does exist: http://hno.huma-num.fr/browse?idType=319
