VESPA was built by Cochrane in 1921 for HS Gaselee in London as YN 707.
She was sold to Harrison (London) and renamed MARKROCK in 1946.
Don't know where she went to after that.

Photo as MARKROCK

Neither do I!
But here she is as VESPA
Seems to be towing a submarine in upper view with a large crowd on the vessel (naval?) across the dock.

I think the second photo that you have posted is of the later VESPA, built as the BRODSTONE in Aberdeen in 1934. You will notice that the foremast is well forward of the superstructure. BRODSTONE became EVELYN BRODSTONE in 1934, VESPA in 1946 and WENDY ANN in 1974. She is still sailing, out of the Isle of Man.
