Main component is battery holder LY21448 (compatible with LY21446).

The item might also fits GR-D340 and GR-D345, but you should carefully check. Incompatibility cannot be reason for return.

The assembly will be removed from a camcorder JVC GR-D320E with defective mechanism.

Check my other listings for other parts of the same camcorder. Let me know if you need an unlisted part.
