This picture is of some unknown Canadian insulator markings that have me stumped. Even some of my Canadian Insulator collecting friends have had little luck. I would love to solve some of these marking manufacturers. The top row are wire holders. The first ones are marked Hayes. Hayes /2466, Hayes really nice glaze, Hayes ink stamped on side, Hayes 2464, The next three are marked LC. L and C in circles, LC/ 1425, LC/ 1928, The next one is marked Henley. It came from Great Britian but that's all I know. The last is a large cleat marked F.M.C. On the bottom is cleats and spools. The first cleat marked Hayes/ 2573, Next spool marked Hayes/ 2201, Next is a cleat J.E.M. Co. (has a Smith & Stone marking on bottom), this small spool is marked Manitoba Bridge/ 1290 (on bottom HP Made In Canada), next is LC/ 268? (HP made in Canada on bottom), after that is spool marked Hayes/ 1608 (HP made in Canada on bottom), Next small spool Hayes 1603, Last is a cleat marked LC40 (made in Canada HP on bottom). I have found very little info on Hamilton Porcelain Company LTD as well. Any info or pictures appriciated.
