it appears to be 1913... scraped on the date with my knife. The 3 looks a lot like the 3 for the weight, so it could be 1918 unless they weren't making them in the last year of WWI?
The horn looks like it was repaired with GIANT rasp....pics in the morning.
Question....???what's the proper way to fix the mushroomed sides? Pien them up? Or, grind em off?? Gasp, cough, cough....
