mid-century vintage Italy table lamp, ruby/crystal, Italian art glass

Mid-century modern vintage art glass table lamp, made in Italy, we think? We haven't been able to find a maker's mark or label at all.

This measures 23" to the top of the light bulb socket, and 31 1/2" to the top of the finial. (The finial is very fancy, silver finish metal with round crystal glass orb. We aren't certain that it's original to the lamp, as the rest of the metal fittings have a gold or brass color.)

The wiring works, but it showing some age. The glass parts and lamp base are in very nice condition.
