Cd 154's found in the mountains of Spain. There is about a 50/50 mixture of C.T.N.E (National Telephone Company of Spain) and R.E.N.F.E (National Network of Spanish Railway) embossings. The telephone marked units were found on overland toll leads and the R.E.N.F.E. embossed ones along railways. And, yes, that's a Hemingray 42 first on the right in the front row! I'm going to repatriate it and keep it with my Spanish CD 154 display back in the states, lol. We found a few of them on a toll lead.
