Ooops: Rechecked and it is 75mm instead of 7.5mm. 75mm is 3 inches where 7.5mm is 3/8. Looks like a cut and reglue. Just a senior moment. The little picture measured the 3/8" but read 75mm and then on my mm to inch ruler the note equaled the 3/8". I usually use 1/2 oz at about 6 inches width with epoxye then repeat at 5", 4" and 3 inches center strip. Little more time consuming but seems to give a smoother smooth finish.
