I got an offer to trade my used Frogskins with an X-Metal XX in X-metal. I went to see and found that the glasses is in good shape, looks legit to me. Just that the nose bombs are lost and been replaced with a stretched Juliet's. I checked the serial number and wondering how many types of font are there? As it was quite small and last digits are faded. I do have a polished Juliet and the font of the serial is just like every other X-metal I've seen. Any of you have XX ever see font other than pic below? (Picture from Google)
