Using the same frame to create multiple models by varying the component spec and cosmetics was a common practice among mass market brands. It allowed companies to hit different price points, while striking a balance between reduced consumer costs and increased profits.

​​​​​​​The classic example of doubling up on a frame is the Peugeot AO8 and UO8. Adding a few brazed-on fittings created the AE8 and UE8, so you could even argue that the basic boom era Peugeot frame design performed quadruple duty.
