Default Identity of two vintage drivers?

On one small speaker it reads : 3D-2Aa
Cr-77
Super Tweeter
IMP Japan

And on the mid/tweeter speaker it reads: 0704Da
CR-90. 88
Tweeter
IMP Japan
They are both alnico, with dark paper cones.

They are part of a 3-way system. The woofer appears to not be alnico ... annular magnet

Can anyone enlighten me? Who made them? Are they worth anything?

Default more info

They come from a speaker called a "Criterion 88".
I read on another forum that they may have been Lafayette.
But the question remains: who manufactured these drivers?

???

Criterion drivers are Coral OEMs... The picture has the back of the lovely 2" cone tweeter (are yours cream or dark? I really like the looks of the cream) and the 1/2" alnico dome super-tweeter.

Which 8" wowfes did you get... ceramic or alnico? Ovals between the basket legs or 2 (>) sizes of circles? It makes a killer wide range in an OB.

I'll have at least impedance curbes on these, and i have a (dead) super tweeter with the friont removed.
