what does the series of letters and numbers mean at the end of the mold discription mean? For instance 225-70-RN- B1. The B1 or BN3 or C3 etc. There are several molds in many caliper with these letters and numbers.
If they are not listed in the ” Abbreviations and Mould / Casting Terminology ” sticky , they are said to be Control Numbers for Inventory purposes…. If I were ordering a mould I would include it….not sure if needed but why take a chance. Gary
