The “labels” were probably “contains lead - tetraethyl” signs, depending on the bolt pattern. You might also be looking at a bolt pattern for a manufacturer ID / serial number tag (depending on location).
Measure the bolt patterns and try to take some pics and post both the measurements and pics here. I’m sure we can figure it out with a little more info.
