Dovetail plate, 2-1/2" x 7". Has numerous threaded holes. Got this with TeleVue 101 and have no need of it. I think this is TeleVue part
#ACI-0700 which retails for $66. + shipping. My price is $45 including shipping in US.
Previous owner said he used it to couple to Losmandy G-8. Has four tiny dots in finish--perhaps from point of attaching screw? Otherwise like new.
Thanks for looking. Hope someone has a need for this.
