  One often sees the Bluebird referred to in guidebooks and on internet sites as the Model 506 ... Not only did Sparton "proudly announce Bluebird Model 566" in one of their brochures but there is also the matter of their approach to model numbering. In June of 1935 they announced to the world their line of 1936 "regular" models, the entry level set being the Model 506, a small 5-tube ornamental mantel set priced at $29.95, the cabinet being made entirely out of wood. Later that year they unveiled their "Teague" line of upscale models, and shortly after that the Bluebird. Now, Sparton's model numbering system at that time used the number of tubes (often not counting the eye tube) as the first number, a model identifier as the second, and the last digit of the model year as the third. Key here is the fact that the second number was chosen to create a unique identifier, ensuring that no two models ended up with the same number. Thus, the 5-tube 1936 mantel set was the 506 and the 5-tube 1936 Bluebird the 566...
