I see some numbers on the basket frame, underneath the magnet, to the left, where it screws into the baffle. I have a pair of 1957 Jensen woofers that have their model number stamped in the same place.
I was googling the HF driver R-106 and came up with a reference to ST 875 H222. Following that, it looks a lot like the ST 875 H222 in this post
Here's a pic of that speaker which, if not for the bell cover, lots a lot like yours. Like Dr B said, the magic numbers are stamped on the frame, obscured in your pics.
If you Google Jensen h225, a picture shows the driver front and back. Looks like it is a Jensen h222 without the back made for the Japanese market. The website (gzhifi) doesn't come up.
