Photo of 1866 British Euphrates Class Troopship

I had this framed photo made from a large glass slide I put in a safe place that I can't find now!!! Euphrates class British Troopships. To carry troops and families to India!! They built 5 of them. Malibar Serapis Jumna's Euphrates and Crocodile. I don't know which one this is?? It's moored at Malta. Notice What I believe are Frigates in the background. Blunderbuss they were lightly armed with 4 lb gun's. Google it for interesting reading. Sorry about poor photos but it's hard to take pics threw glass with a bad phone camera!!
