Newly Acquired Palm Beach Model K557

[Efenglom]

Trying to find out if anyone knows if there is a place to reference the model number on the inside of a Palm Beach suit. The size and ownership label on the inside breast pocket has "model: K(superscript)557" I am wondering if with this reference I could find out more about the suit. It appears to be a natural colored mid-50s two-button with patch pockets, pleated trousers with watch pocket.

Any help would be appreciated.

I personally can offer nothing. Pics?

How about a picture of the label?
