Need info on Olmo Sintex
 

I just acquired a very clean Olmo Sintex frame, it is constructed of Columbus SLX tubing and has 126mm rear dropouts. I would like any information on this frame, especially dating the Sintex model and it's geometry. It appears to be of late 80's vintage, but I cant find anything which would allow me to properly date this frame. Prior to building it with a mix of modern Campy and Shimano 9 speed, I'd like to know how this bike was originally equipped. Also where does Olmo stand on the food chain of classic Italian bikes.

Thanks
