Woodstock HP2x replacement feet needed

[calc-calcs]

Hello,

I am looking for a pair of rubber feet (or all 4 if possible) for my HP25. The ones that came with the calculator have not aged well possibly due to the environment in which the calculator was kept for a long time, or for some other reason. I also have a HP21 which has feet that are in good shape so I know well what needs to be done to pull these out gently without harming them. But the rubber of these other feet turned very sticky, lost the springiness and have now the consistency of hardened chewing gum so they deteriorated noticeably on the first pull out to open the calculator, even tough I did this very carefully.

Not that the feet are absolutely necessary, but it would be nice to have them. If anybody has a pair (or all 4) and would be willing to part with them, please let me know.

Thanks.
Alex
