Bencher BY-2 Chrome Iambic Paddles
I purchased this one new from R&L Electronics in 2008.
Same as the BY-1 with a chromed base.
From Bencher's website:
"A paddle that is perfectly responsive, light to the touch, a paddle your fingers float over and become as one. A perfect paddle is one that the operator forgets as his/her thoughts reach out, flawlessly and smoothly translated into perfect CW. A paddle with definitive yet subtle tactile feedback, friction free return, and perfect closure on every dot and dash."
