Hello everyone! I have a mystery for yall i hope someone can help with. I own a cat EL 400 eliminator im reworking. i stripped the frame for repainting , i did not use anything that would damage the metal in any way, i searched the frame very carefully and could not find a production date or serial number anywhere. is there anyway to tell when it was made?thanks guys for any help you can give. has anyone one else run into this before ?:shrug:
