Pair1211A speakers from the 1970's - any worth

[Philbo]

I have a pair of Vintage 1970's 2-way, 4-speaker floor type 1211A Portable Column Speakers for musical instruments. Designed for use as both an onstage monitor speaker and an extremely compact reinforcement speaker it was developed for small stages such as small halls and night clubs. The design consists of three 8" full range 403A cone-type radiators and an HF-206 horn driver. By design they disperse into a wide horizontal pattern. They have a 1/4" input jack and take standard 1/4' speaker cables. Rated at up to 50W into 8 Ohms. Weight = 20kg size is 35" x 11" x 14"

Would anyone know what, if anything, they may be worth these days in Good condition? Also are there any suggestions where one might best list them?

Not too old to rock and roll but too old to mule around 45lbs of speaker these days.

Thanks Philbo
