I have the serials off one of my d130s, the serial on it is 87681, the cone (if i am talking about the right thing) has a 21057 number in white ink on it. the 075 in the case has a serial of 76744, Previous owner was Don Walker in Muscle Shoals, AL, he bought them new, new owner, Don Walker II.

I have been reading up on these products and what is weird is that both of these speakers, the 075 and the d130 both have 8 ohms on them, but from what i understand is they are actually 16 ohms? just curious, thanks guys, when do you think these d130s were made and bought, late 60's?
