That floral engraving pattern was introduced in mid-1915 as the No. 1 1/2 but by 1919 had become the No. 1 as Ithaca thinned out their plethora of low grades. Likewise by the 1919 Ithaca catalogues all composite barrels were gone. This gun is a fine example of never say never in these old guns. Those barrels are much finer then what would have normally appeared on a No. 1 1/2 or a No. 2. The No. 3 normally came with Chain Damascus barrels, so these were likely originally intended for a No. 4 or higher.
