Seeking help on identifying this small plate and any know value?

[treasuresoftime419]

This plate looks like "flow blue" but the decoration is brown with an impressed FB on the back. Crack and some crazing and pin prick sized tiny glaze pop. Is is majolica, salt glaze, flow brown (for lack of a better term ???) and what does FB stand for? Again I have spent time trying to research this unique plate before coming to the board for help and have found nothing. Even if just a primitive or country decorative value...I have a hard time throwing anything 'old" away....

Thank you in advance!

it is difficult to tell the technique whether transferware or underglaze painted.  it is not majolica or salt glaze.  Have never seen an ID for the FB mark.  It is not 'flow' as the decoration does not run under the glaze.  With the damage the value would be very low, not much value even if not damaged.
