But, like a lot of 'vintage' items coming to market in this boomer twilight, whoever is holding the tool has a much higher estimation of the ROI than any buyers can math out.
Were I advising, I'd counsel the owner to thoughtful negotiation to drive to an acceptable price, because the value of the asset is decreasing as R2 learns how to work around old tool limitations.
While the existing molds would be close to running, any savings would evaporate after shipping (offshore), mold validation, cutting missing inserts (clear), GM licensing, packaging, printing etc.
A '66 Apache would be an ideal Craftsman Plus subject; it is configured exactly as the new subjects are. (A bit surprising, in retrospect that it was not offered as such in the day...) It could stand on its own, be part of a gift set with a trailer and race car, etc. it's not hard to see a future.
Ultimately, I could see R2 leadership cutting their own fresh new tool, which would slash the value of the old tool to somewhere around scrap.
