There is very little I know about Calliopi but I hope my sources are correct. It was a Greek ship that graced the Greek seas for about 14 years.
According to my sources, she was built as steamship Scotia by W. B. Thompson of Dundee, Scotland in 1875. She belonged to the Dundee, Perth & London Shipping Co. which was formed in 1826 when the Dundee & Perth Union Shipping Co. merged with the Dundee & Perth Shipping Co. to provide passenger services between London, Glasgow (via the Forth & Clyde Canal) and Liverpool. voyages were also made to the Baltic and White Seas for flax and timber. In 1834 the company started using steamships on the Dundee to London service, in 1857 the fleet of the Dundee and Hull Shipping Co. was taken over and in 1859 ships were first used in the fruit trade from Greece and Spain.
In 1880 she was sold to France renamed Finistère. As such she belonged to the Societé de Navigation Cotière pour l' Afriqe du Nord and covered the routes of North Africa (from Aliers to Oran and Tunis) from 1880 to 1918. She had 243 tons originally and was expanded to 453 tons. She had a length of 54.7 m and a width of 7.3 m

And here is a set of schedules of the company's ships....

The ship seems to have arrived in Greece around 1918, not 1924 as mentioned elsewhere.
