Early Class M cabinet variants

[EKzono]

Hi,


There seems to be at least 3 variants of cabinet on early Class M machines.

Mine has the cabinet with the fewer and bigger corner connections. See first (top) machine on illustration from the Marty book.

But I haven’t seen any other of this variant so far on the machines of fellow collectors.

Anyone our there with a Class M with same style cabinet?

The “corner connections” are called ‘finger joints’.
