My breadmaker is missing the kneading paddle. Where can I find a replacement?

Hey all.

Sorry if this isn't the place to ask, but this appears to be the community best suited for this kind of question from what I can gather.

I recently bought a breadmaker at the thrift shop for cheap. While I initially was worried that it didn't work as intended when the piece that would turn the kneading paddle didn't move from the start as expected, I found a video for another breadmaker in the same product series, and discovered that it simply takes some time to start the kneading portion as it undergoes a pre-heat step beforehand.

While I've tested and seen that the breadmaker itself works, the one thing preventing me from operating it is the fact that it lacks a kneading paddle. This is the first time I've purchased a breadmaker, and as such, I'm a little lost as to how to get my breadmaker operating as intended with a new paddle. I would order from the manufacturer, though the issue with that is that my model breadmaker is fairly old, with the instructional video for it having been ripped from VHS and dated as being from 2000.

I do not want to throw this thing out. I would much rather get a new paddle as this thing seems to work like a charm 24 years later, and I am trying to be more environmentally conscious by purchasing second-hand goods as well as minimizing the amount that I throw out.

Unsure if it will do anything to help, but the model breadmaker is a Black & Decker All-In-One-Deluxe Automatic Breadmaker, Cat.No. B1640, Type 1. Any and all help is appreciated in advance.
