Myles... I have a speaker that I would like to know who made it. We've put it in a Peavey Classic 30 and love the sound... Here's all the info I could get from it... The speaker came from a 1972 Alamo Futura Reverb 2567. On the back it says: 12L A50 137 - 7242 Application Engineered for Alamo Electronics On the back of the cone is: 1252 T (I think it's a "T"). Thanks... Billy
