Where to find old png2ico PKGBUILD it was dropped to AUR?

All, Cleaning up old packages, I still need the png2ico utility. It is no longer in AUR replaced by elphicon which uses that abomination electron. I need to know if the old PKGbUILD for Arch png2ico still exists in some historical form somewhere. It would save writing another. What say the historians, does such a thing exist? -- David C.
