Simplex plastic front derailleur broke.
Shifting gears was just too much for the 35 year old plastic.
Need a simple strong reliable decent non-index for a front double.

Any recommendations on what to look for?

70’s Vintage would be preferable, but I just want something unbreakable and good.

literally any one for a double with the right pull type and clamp size
