Instead of portable, which implies being able to be carried, it is mobile with the wheels implying movement. It calls to mind a tea cart as much as a horse-drawn wagon. I'm surprised there is not a shelf on the left modeled on the driver's seat.
Here is a factoid about "Ye" as in "Ye old." It is not pronounced YEE, but rather th'. The Y-shaped letter is actually the old English letter Thorn which closely resembles a capital Y, but is not the same. Today it exists only in Icelandic. It fell out of use in machine-printed English because the letters for type were generally made outside of England so it was not in the character sets for printers.
