Steam locomotives SEK Ζε71 - Ζε74, exCO, exCFFH, Hanomag

[LefterisK]

Good evening to you all!

Searching my Facebook saved posts I stumbled across a photo of the SEK No. 74 steam locomotive, in the group HELLENIC TRAINS AND RAILWAYS. According to the author, George Papasouliotis : "Η ατμάμαξα Νο 74 των ΣΕΚ το 1964 στην Αλεξανδρούπολη ( από Ebay)". The description translates as: "Steam loco No.74 of SEK at Alexandroupolis (source:Ebay.)".

Following some research, I found a builder's photo in Flickr from user "Historical Railway Images", of the No.72, and a note in the Wikipedia page of CO that those locos were classified as Ζε from SEK in 1955.

Does anybody have more info about those 4 beautiful locos?
Also, do we have any info about models of these locos in HO scale?

Greetings,
