Machine details
The SINGER 7448 is another CB Cosmo/Confidence model whose current manufacturer coverage is strongest on accessories rather than historical product specifications. SINGER's current pages explicitly support the existing Class 15J and presser-foot relationships, and foot control SKU 416436101 is listed for the 7448. SINGER service documentation identifies a specific electronic distinction: 7448 and 7468 use switch-board component 87548. That is useful when evaluating repair parts because other members of the same service-manual family use different board numbers.
Compatibility context
A user looking for a bobbin or foot gets the current CB compatibility. A user trying to identify an internal electronic part gets the 87548 service reference. Those are two different tasks with two different source types.
