I just acquired a Structo 750 on a stand. It was in a school, headed for the dumpster, and then spent 20 years in the art teacher's basement. It has capacity for 8H , but there are only 4 which are in the 1-3-5-7 position. The other harnesses if there ever were any are long gone. I have looked at the catalogs on yahoo, but still can't figure out how to get the remaining harnesses out and repositioned.The frame that holds the harness is bent so I think the others were removed forcefully. Also, can you move heddles from frame to frame? I know the notched heddle bars lift up but couldn't move them enough to get heddles off. Thanks for any help anyone might offer.
