Can you identify this?

Your roller looks a lot like our 81-057 at first glance, but it looks like someone swapped out the internal housing (and presumably wheel) with the internal housing from an entirely different roller. I have no idea why that would have been necessary. I'm aso not sure if our 81-057 will work as-is or if you will have to do a similar kind of swap. Either way, this product appears to be our best option. Look it over and see if you think you could get it to work.
