Looking for the font of an 70's old time radio (Radio Eldorado)

[Alfredo LP Manhães]

Hi all,

 

I'm building a webpage about extinct FM brazilian radios and found the logo of "Radio Eldorado", from 1970s. I would like to identify the font to restore it in Corel Draw. Could you help me? Thanks!

Despite a low quality reference it looks very much like Eurostyle Extended.
