I came across this item in the Marine Engineer of Jan 1883, which refers to "Dunstone-on-Tyne Shipbuilding Co". This is a new one on me and I presume Dunstone should be Dunston. Anybody got any information about this yard and its ships?

Just realised that I didn't attach the photo (Duh!)

Sounds like an interesting little vessel maybe similar to the 'puffers' especially to trade through the Forth & Clyde.
Seems like, on this evidence, you should add it to the Tyne site, Dave!
