Hmmm. Wasn't there a Model 1889? There should be more markings on this, especially manufacturer marks. My saddle has marks on both sides of the sweat flaps (Schweißblätter), unit mark and date on the inside middle (U.R.20 1895) and on the outside high up under the seat flap (F.Cobau). Normally, a crown on leather items denotes a Bavarian B.A. acceptance, but that would appear with a corps Roman numeral beneath (I., II., III.). So, Hardy may be correct. Anyway, it's a good guess.
