    Good Day All,
    I recently picked up a new addition to my collection and thought I would share it with you. . It is an 1850's Fremont NH John Brown Underhammer rifle. The seller says it is a .40 cal and is a very heavy rifle. I have not received it yet but I do have pictures. It is missing the front sight but the rear tang sight is still present. I hope to get this rifle back into firing condition so I can take to the gun club. I will post more pictures soon. pix078538302.jpg pix185070597.jpg pix285755961.jpg pix308102046.jpg pix326113407.jpg pix433674080.jpg pix543195404.jpg pix787673157.jpg

    I really like Underhammers, especially New England and target rifles. Can you post better pics of the sight and is it missing an elevation rod?

    There is an article about Andrew and John Brown in the June Muzzle Blasts.

    I probably should have just hit the like button on Mark's post as there isn't much for me to add. I do like underhammers and own 2 originals as well as several H&As though I never seem to get a chance to shoot them. I too believe there is a missing piece in the rear sight that would be used to adjust the elevation.

    My very first rifle was an underhammer, and I still have it. I took a lot of game with it and it got fired a lot. It's now retired and out to pasture; it earned that.

    It is missing an elevation rod and I do not know what one looks like. Can you help?

    Typically they are a threaded rod, of appropriate length, and have a unfurled disc attached to facilitate rotating the rod. As the rod rotates the sight goes up and down.

    The best way to determine what the adjuster looks like is to research Brown's underhammers as they likely all have the same style if they have an adjustable rear sight. If it isn't possible to find one of his guns then an examination of the rear sight and tang would probably suggest a workable solution.

    Looking at the rear sight tang you see a metal plate with a small hole that slides up and down when you loosen the screw on the side. Could the elevation rod be a stationary support or is the sliding plate a coarse adjustment? If I can find a photo of the rod I can make one on my metal lathe.

    Good news guys, The seller said the bore was rated at approx 80%. Well I cleaned the bore and was pleased to see a pristine bore. The rifle does appear to be correct for the New Hampshire rifles of the time. This will be a nice shooter.

    NIce rifle! I can't tell from the pics, but I'm assuming the breech plug is surrounded by the wrist of the stock? Does it have a frame extending down the wrist?

    I could not find any photos of an rear sight adjuster so I made one on my lathe. It will do for now until I get the correct one.

    The sight adjustment screw looks just fine.
