Old Cerwin Vega Model 210

I have a pair of model 210 Vegas from 1972. Does anyone have any information on these speakers as Gibson who has acquired Cerwin Vega does not? I have loved these "Texas Bookshelf" speakers for long time.

I think that that is the same model my Dad has in his home - they are very nice. I used to have some floorstanding Cerwin Vega's before I got my Cornwall's. I always thought that Cerwin Vega was pretty much the best mid-fi speaker line.
