Hell, I'd just remake the part and do it right. This is way more cost-effective in time and $ than waiting around bidding and receiving a vintage side rabbet plane.
In my early days of wood working there was a lot more time in my bank than there was money. Fixing mistakes is often how one learns to avoid mistakes. Much of my learning, that wasn't from reading, comes from making mistakes. My learning is still ongoing.

A side rabbet has been a useful tool on many projects. The width of my plow blades do not always match the thickness of my lumber. Sometimes they are nice to knock the fuzzies off of a groove's or dado's walls when working with swirling grain.
