Hello and welcome to another Mattel Football clone, there are so many of these.
|
||||
The 1655-024 one came from an unbranded handheld, but comparison suggests that
|
||||
it's the 'prequel' of 1655A-033.
|
||||
|
||||
The 1655-024 version looks and sounds the same as Conic "Electronic Football".
|
||||
Comparison suggests that this is the 'sequel' to 1655A-024.
