Thanks gents for your crucial updates.

The ex Milford tug Reagarth 1964 6407509,now Panormitis is still operating at Piraeus at 53 year old, also at Souda Bay last year was the ex Brigadier 1976 7400936 now Perseas, ex Cory Towage at 41 year old, used to recover the towed array`s from visiting submarines.

Also of interest is the tug ahead of the Poseidon which is the ETHY VI, previously Alexandra Towing's HENDON

And previously the MARSEILLAIS 14, built in 1964 (info c/o Miramar Ship Index)

The Unknown Tug is "Θ.Υ. Ι" ("TH. Y. I") (ex KARAPIPERIS IV, IMO 6405604). Owned by "Sea Services Shipping Co.", the same company that has the "ETHY" ships

The MILLA A Imo.8878441 was built in 1917...that is 100 years old and still at work towing fish cages in Maltese waters. so you can say "wowee x2" MattyBoy, I have posted several photos of her.
There could be others which I am not aware of.

Shame - I thought I'd hit the jackpot with this one !

MattyBoy: There are many tugs much older than this still working away.

Wowee !! She must be the oldest tug still in service then, at 47 years old !!

Nice one MattyBoy the ex Milford based tug the Graygarth, her sisters were the Glengarth and Greengarth, nice to see she is still around.
