I just picked up an old Peter wright. One side reads p.wright &under that says warranted. The other side has the numbers 1,0,&8.i believe he last being its weight at 80lbs. I haven't weighed it though. On the bottom front between the apron its stamped either 11 or Roman numeral II. I'd love a little education on the significance of the stamps&its age&value. Anything would be very very appreciated.thank you
