I was not expecting to add anything else this year after an already expensive year but this rifle came up and there are too few examples for me to have turned it away.

Farrow Single-Shot rifle -- no serial number; 30" octagonal barrel; .32-30 Remington caliber; excellent bore. The rifle's action is nickel-plated brass (maybe bronze). The front sight is a windage adjustable sight and the rear sight is a Winchester vernier tang sight whose base was curved to match the upper tang.

This rifle is shown and described in Richard Chamberlain's article, W. Milton Farrow and his Rifles, in the 1962 Gun Digest.

If anyone knows the timeline of ownership, please share.

Ditto on the rifling... Joe make sure there isn't a number stamped on the front face of the action, you may have looked already...

Cool rifle too!

Neato! Is there room for a firing pin in that block or is it built into the hammer?

Joe,
That's what I wanted to see.  I read somewhere that Farrow in his later years determined that the number of grooves and lands made little difference in a barrels performance, I'm guessing this is a later model.  The Farrow stamp on the barrel is something too, maybe someone will chime in here and shed light on the particular stamp?  I've attached a picture or two of the bore on number 100, the serial number stamping and the barrel stamp.  Little bit of a contrast as Farrow went along.
Again thanks for sharing, that rifle is very intriguing.

I have a copy of a letterhead stamping of Farrow from Brattalboro, Vt.  It looks just like the last part of the barrel stamping.  Might be a coincidence, but maybe not.  Don't know where I got it.

Joe-Got curious about the Gun Digest connection and looked through the auction catalog of John Ambers collection that was auctioned off in November of 1986. Lo and behold on pages 108 and 109 a Farrow matching yours was listed. If interested PM me your email and I'll can scan you some pictures. Steve

Thanks for sharing, nice rifle and bit of history. Really like the look of the Farrow’s.

A thought about the barrel on this rifle:

On p,140 of G. Scott Jamieson's "Bullard Firearms", we are told that the interior dimensions of the barrel of a rifle fitted to a small-frame Bullard repeater chambered for the .32-40-150 Bullard cartridge were:

Twist: 1 turn in 16 inches.   
6 grooves, depth of groove = 0.004", width of groove =0.080", 
Bore diameter = 0.306", Groove diameter = 0.311"

Farrow was an employee of Bullard for the entire calendar year 1884.  IN November 1884, Bullard was in serious financial trouble and laid off most of their employees.   

Think this non-Farrow barrel was from Bullard's barrel inventory?  I'm not implying that Farrow stole it.  My suggestion is that he bought it, rented shop space from Bullard, and helped keep key Bullard staff working by paying them to teach him to be a machinist and to make the prototype.
