It's really hard ta tell from yer pic, a wool felt patch of da 4025th signal service group would indeed be very rare................... Quite a bit more than what da current listing is at............................. The Pacific arena had sum strange felt patches, but yours just looks incorrect by shape...................... Should have sum simple stiching around da border an the backside is one of the best ways ta see how it may have been sewn or by what type of machine.............................. I've seen sum rough shaped patches, sum that look hand sewn, frum WWII, normally distorted from trying ta hand sew da borders.................................... Just going by shape I'd say repop by glance. before or pre interweb repop, Doesn't mean that the rest of da stuff ya have isn't real.................................... Just means the show it was purchased at sold sumthing that was hard to find or match because it wasn't a common patch.......................................... Just my opinion
