My sunburst Rangemaster Goya guitar was probably made by the "Polverini Brothers" of Italy (not by EKO as previously thought) around 1968 or 1969 as best I can tell. The serial number is N5139. The model number is not available on the guitar but I believe it may be the continuation of the Rangemaster model 107S which is shown on page 14 and 15 of my 1967 Goya Guitar Catalog. "Click here" to go there. More information about Goya can be found on my "Goya Information" page. If you have any additional information about this guitar model or the "Polverini Brothers" and their connection to Goya please email me. Thanks
