Vase, octagonal, antique B or FB mark

Pair of Vases, octagonal, antique B or FB mark
Vase looks to be transfer printed in blue with over glaze hand painted red.
Printed mark looks like B or FB and a moulded 3.
My guess is it’s European late 19th C or early 20th C
Any ideas?

It looks like it may be tin-glazed earthenware, so could well be French faience.
The f in the mark is vaguely similar to some Fourmaintraux, but not a style of
decoration I have seen before, or associate with them, but much faience was
cryptically marked in blue like your pot.

could it be one of Boch Frères marks ?

Thank you both - couldn’t see it under Boch Freres marks but did see some gorgeous things by them!

It could also possibly be one of the Delft potteries.
