op 1417 Collimators for Optical Instruments,  I have been searching for the Ordinance Phamplet with no results.

I'm not sure I understand what you're looking for, but a Google search took me here: https://books.google.com/books?id=ksTDAgAAQBAJ&lpg=SA8-PA8&ots=c0WlGpzjPL&dq=op%201417%20Collimators%20for%20Optical%20I…

I processed the Ordnance Pamphlet collection more than a decade ago, and it appears that the Navy did not transfer to NARA any of the OP's between 1200 and 1553.  I wish I had a better answer than that.

Rather a late response, but hopefully better late than never...

The Maritime Park Association has a Finding Aid for RG 74 (ARC Identifier 575643 / MLR Number A-1 1022):
NARA Record Group 74: Records of the Bureau of Ordnance, 1818 - 1967: Ordnance Pamphlets Finding Aid

It looks like their "ID 1486" entry may correspond to the pamphlet in question:

It doesn't look as if that particular pamphlet is in the online ARC catalog (the Maritime site has a few manuals digitized, but I don't see this one on their site either...) so it would probably require either an in-person visit, hiring a research, or (if it's the type of record you can order a copy of and if the above information is exact enough) attempt to order a copy:  How to Obtain Copies of Records | National Archives
