This is a no-brand Bigsby-type arm. The size is slightly different from the original, and it's heavier. Also, please note that it doesn't seem to fit with a Vibramate. It has been used a little, so there are marks from the strings. Please check the photos. Recommended for those who want to try a Bigsby-type arm at a low price. - Color: Black - Included: Spring, mounting screws - Material: Zinc alloy
