Stanadyne DB2-5070 Diesel Injection Pump Data Plate - Model & Serial Numbers

This photograph shows the metal identification data plate riveted to a Stanadyne diesel fuel injection pump. The plate carries the STANADYNE brand name across the top, with the model designation "DB 2 · 5070" stamped in the field labeled "MODEL NO. & R.P.M." Below that, the field labeled "SERIAL NO. & MFG. NO." contains the stamped numbers "7584257" and what appears to read "18163509" (possibly with a trailing digit). The bottom edge of the plate reads "STANADYNE AUTOMOTIVE CORP." followed by "WINDSOR, CT," identifying the manufacturer and its location. From this plate a reader can identify the exact pump model (Stanadyne DB2-5070), its serial number, and its manufacturing number — information needed when ordering rebuild kits, seeking pump calibration specifications, or verifying that the correct injection pump is fitted to an engine. The photo is very dark and taken in an engine bay, so surrounding hardware is not identifiable; some small text near the top right of the plate (likely a patent notice) and the very end of the manufacturing number are not fully legible. No vehicle year, engine application, or RPM value is stamped or visible on the plate itself.
