Have really been wanting one of these Hemingray 19's for my collection for some time without paying a fortune. Got this one for eight bucks at a nearly new antique and junk shop near by. Also picked up a couple of CD 145 Brookfield crebs for the same price each. Didn't mind paying that price when I knew the Dark Olive Green was quite a bit more then what I would be paying for all three. I also wanted them for my collection because of the shop numbers. Pictured is a number 7 and a number 16. The number 7 has a large backwards 7 along with a much smaller correct number seven. The 16 has a backwards number 6 and also has a correct 16 which is just slightly smaller. I've never seen any of these crebs with both the correct and error shop numbers. Has any one else seen or have any. If so what are the shop numbers. Email me if you do or know about these insulators. Thank you!
