Help identifying family furniture?

[Notorious PhD]

Hello and thank you on advance for your help. This full size bedroom set belonged to my great grandmother and is been around for at least 50 years, but likely close to 60 or 70? I've had it for about 30 years and would like to know a little more. I'll add the pic with the dresser mirror and the headboard and footboard later.

The chest has two marks on the back. L-11-CB and L-11-CH. The dresser mark reads L-43-DR.

Any ideas? I checked most of the drawers and haven't found any marks either on the inside, the back, or the undersides.

I can't you a thing about it other than it's beautiful.
