Searched a local flea market today and found 2 of these CD 154 C.T.N.E. Spanish glass insulators!! This one is a nice light green with some unusual embossing. On the front skirt, C.T.N.E. is also faintly visible directly above the prominent embossing. On the rear skirt, ESPERANZA S.A. is visible lightly above E.S.A.

Has anyone seen this before? I paid $1 a piece for them, but haven't been able to find out anything else regarding value. Can someone point me in the direction for info on these foreign pieces??
