This is a nice snap on HB300 for piece file set in a C300 kit bag. These files have handles that are removable by unscrewing them. Overall length of the largest file is about 17 and 1/2 in, the next one is about 15 and 1/4 in the third one is about 13 and 1/4 in and the 4th one is about 10 and 3/4 in. The file lengths are the smallest 6 in the next one is an 8 in the third one is a 10-in and the fourth one is a 12 inch file. The two smallest files are both marked Nicholson USA. The smallest one is a mill smooth, the second to the smallest is marked Mill bastard they two larger ones do not have marks on them but they are the same as the mill bastard. The handles are marked under the bolster Lutz twist on. The second from the smallest handle is marked skroo-zon. No owners marks are found on any of these files nor are there any owners marks on the kit bag. Kit bag has good snaps and is in excellent shape no tears. These files are all used and have some wear to them and some light corrosion but nothing deep that would affect the use.. I used a magnifying glass to better get the focus of some of the close-ups so there may be some distortion.View photos of this nice file set! Look up!
