First, if you do not have a owner's manual, contact Colt. If they have one they will send it to you or direct you to a site to download one. If Colt is not helpful, check on line auctions, estate sales, garage sales or pawn shops. In the meantime, I would suggest you find a gun shop/gunsmith and ask for help.

The Colt AR-15 SP1 with the serial number 85440 was likely manufactured in the early 1970s. Colt's SP1 series was produced from 1964 until the early 1980s, and specific serial number ranges can help narrow down the production year. For exact dating, consulting Colt's historical records or a reference guide on Colt AR-15 serial numbers may provide the most accurate information.
it was made by ITHACA (not colt) in 1943.................If your slide reads Colt, then sometime down the road a colt slide was put on your Ithaca receiver...............that is not unusual to have happen.................
