I ran across a few early parts on eBay this morning. One being another hand throttle for a mere $2000.There are a few other parts listed and all pretty high priced.  The ad says it is an auction broker out of GA that will be selling off a hoard or 69-70 parts from a 71 year old collector. Must be the retirement fund. They also claim to have a 69 barn find HLS30-00061 that will be posted in the future. Says they will be listing many items over the next year. https://www.ebay.com/it
