At my last radio meet Wed May 20th, on Vancouver Island I was excited to have purchased a AK 20. I have a couple of metal coffin style Atwater Kent radios and an AK 84 Cathedral, but this is the first wooden older coffin style Atwater Kent I have owned. It is a big box model 20, but the tube sockets are bakelite. With four holes for the 01A’s. When I got home I looked online to see that most of the sets online have brass sockets with bayonet mounts.

My model 20 has a 5 digit serial number 37415 and most of the ones I see, with brass tube sockets, have 6 digit serial numbers.
Wondering if this set was made with the bakelite only tube sockets or is there something missing (like brass sockets) that I need to add to make this set
"correct" again.
Any and all help will be greatly appreciated.
