Models 510, 513 and 530 are 5-tube radios: Tubes 1-47, 1-55, 1-57, 1-58 and 1-80.
Models 610 and 614 are 6-tube radios: Tubes 1-47, 1-55, 1-57, 2-58 and 1-80.
IF frequency for all the above models is listed as 265 kc.
I am sorry but this is the only information I can find on these ERLA models. None of these seem to be covered by Rider, and none of them are listed in my 1936 Mallory Encyclopedia. But perhaps with these additional model numbers you can find some information from another source.
