My Husqvarna and Sauer top opening lever, hammer doubles mostly have 75 cm barrels. I consider 75 cm pretty much standard, although have and have seen several with barrels +/- 5,0 cm from this. Some Husqvarna, top lever opening, hammer doubles have 85 cm or longer barrels (even 100 cm!!) and seem to have been popular for shooting the little roedeer (rådjur). These are hammer guns made from about 1890 to about WW1.
Once internal (boxlock) hammer guns became common, seems to me that barrel lenghts were generally shorter, 70 cm or so. Recall 67 cm, 73 cm on some guns.
Handling of older, top opening lever hammer doubles with 75cm barrels, and made by Husqvarna, Sauer or Merkel is, to me, distinctly better than for later boxlock, internal hammers doubles by same companies. But then, I really like lightweight, long-barreled hammer doubles for all my shotgun hunting.
