Bristol Paquebot and TPOs

I don't collect Bristol Maritime marks in general, but do have one or two - the item below because it is a Bristol Krag machine cancel - "BRISTOL / PAQUEBOT".  It is known used from 1913 to 1920.  The postcard was written around Newfoundland.

This next item also has a maritime flavour, with a "POSTED ON THE HIGH SEAS" cachet and landing at Plymouth before receiving a "PLYMOUTH TO BRISTOL T.P.O." single ring cancel from January 1905.  Based on the image on the postcard and the printed text "Antigua-Leeward Islands" I assume that it originated in the West Indies (there is no message on the postcard).

This leads on to a set of TPO marks for the "BRISTOL.SHREWSBURY.&.YORK.T.P.O. / FROM WEST", the top example being the handstamp being used as a mis-sort mark.
