Sullivan, J.It appeared that certain items are parts of photo-microscopic apparatus similar to those the subject of United States v. Leitz (24 C. C. P. A. 139, T. D. 48622). The protests also relate to a vertical camera, •filters, lens holders, and finders the same as those before the court in United States v. Zeiss (24 C. C. P. A. 145, T. D. 48624). These items were therefore held dutiable as parts of cameras at 20 percent under paragraph 1551.
