What is it??????????

This dovetail set-up came with my TEC 140. It was a bit long, a bit heavy, so I did get the TEC 9 inch. This is 13.5 inches long by 4 inches wide. I'd like to know what it is so I can accurately post it on the mart. Thanks.

Looks like a Losmandy dovetail plate adapter. There are many models of this dovetail plate for different size scopes.
