I was kidding Btw.
For the record there are variations of etching and lens thickness for R1 lenses. However your fire lens is suspect not because of thickness variation and etching not following lens curve. It's the fact that the lettering is warped for each character that leads me to believe it wasn't etched with proper equipment or it's a manufacturing defect.
There is a plausible explanation that it may be the fact the machine was misaligned and/or poorly calibrated. Faking these are not impossible and obviously cannot be done by your average Joe. If you're in serious doubt you can always park it next to mine for a free detailed evaluation.
