Gandy parts

[Wrangler1973]

Been raining here the past few days so I've been working on my shop, cleaning and remodeling to for a tractor inside. Going thru some of the stuff I've collected/hoarded, thinking sometime might want vintage tools etc. I have three new old stock Gandy granular applicator rollers. Do these get used anymore? I know my uncle and brother had them in their square balers to apply preservative. 2 are still in boxes the other doesn't. If you/someone you know or knows if an implement company still needs or sells these give me a heads up. I know not everything can be saved or is wanted, I guess it's just that mentality from my grandparents who lived thru the depression and saved/reused whatever they could.

Thanks for any replies or suggestions.
