Ken ... I should have known the Sauer Daly (the model 80) would have been the entry level(?) gun in the early 1900's but had not given it alot of thought as I do not have any Daly catalogs...except for a few early SD&G reprints. Great info you have provided for us Sauer nuts about the model 80 and thanks for clarifing the grade and model for me.

Clair...in regards to Sauer US patent 505006...it appears to have fallen out of use/favor some time around 1900. My thought at this time is that this method of barrel construction was just to expensive to produce. There was a ton of machining time involved in this barrel production method. Guten Tag Jeff
