The thin body (2" deep) Guild T-50 Cordoba was shallower version of the X-50 Cordoba (2 7/8" deep); or, it could be considered a non-cutaway version of the Guild T-100 Slim Jim. Although the X-50 had been in Guild price lists since 1954 (named the Guild X-50 Granada!), the T-50 didn't arrive until 1961, shortly after the T-100. In any case, both Cordoba models were Guild's entry level electric acoustics, but still very nice, playable guitars.
The Guild T-50 was included in Guild price lists between 1961 and 1973.
The Guild Cordoba T-50 was described as follows in the 1968 Guild catalog
Two models engineered to the needs of advanced students. Body size of Model X-50 is 16 3/8" wide, 20 1/4" long, 2 7/8" deep. Body of Model T-50 "Slim" is only 2" deep. Both models have special Guild fast-action Honduras mahogany neck and adjustable steel neck rod, rosewood fingerboard with pearl position markers, short-action professional scale. Single built-in Guild "Frequency-Tested" pick-up has individual adjustment screws and separate tone and volume controls. Both models have nickel-plated non-slip pegs and accessories, plus Guild Strings.
As mentioned above, prior to the launch of the T-50, the X-50 was named 'Granada'. And it is worth noting the similarity between this guitar and the thinline Epiphone Granada first shipped in 1962.
