I used this twice and have since upgraded to a right angle finder.
This is meade part #07426 straight thru, erect image, 8 X 21mm finder with crosshairs that came with my New ETX90EC.
Tube measures 3 1/2 inches long by 1 1/4 in diameter
No bracket, just the finder (as pictured)
in New condition. Comes with original box.
