casters/brackets install @ the factory?

[JUNIOR]

My 81D came with brackets on the bottom to extend the casters out further (to help from tipping over?)
They are painted red & I was just wondering if this was an option with the machine or if someone just added them on at some point?

I believe they were an optional kit that you could purchase.
I have references to handle/dolly kits in some of my machine manuals.
I see this type of dolly on a lot of machines, but don't recall any documentation specifically about them. Unlikely that everyone around the country had the same idea to extend the casters out for better stability.

I didnt like them so I removed them. I wonder if they garbage or worth something to someone?

I'd buy them if you wanted to sell - depending on overall costs ($ + S&H).
Like you, wouldn't want them on a machine I have on display and use. I would put them on a machine in storage as it would make it convenient to move it around.
