The River Tees Port Sanitary Authority

[SAILFIN]

I am presently researching The River Tees Port Sanitary Authority and as of 1916 The River Tees Health Authority.
When I more or less compile all what i have discovered I will be posting it all.
Teesside archives have given Northeastmaritime.co.uk permission to post photos and records regarding this research providing acknowledgements are attached to the information we use.
Presently I'm looking for information about the Launches they used.
Osprey Steam Launch.
Mercie Steam Launch.
Mercie II Diesel Launch of which I have one photo.
There is quite a lot of information regarding The Tees Floatin Hospital.
If any members have information or photos I would gladly appreciate it.
