I visited a former Guzzi dealer this morning and discovered that he still has a stash of loop frame parts including 2 rare left side Ambo covers. One is a pristine NOS white one and the other is undamaged but chrome plated. I didn't inspect the chrome one but he described it as not the best quality chrome job. He didn't give me prices but If you're interested let me know and I'll pass it on to him.
