All the items here are from my grandads tool box, he was a tool maker in in the 30's and 40's I suspect these items are from that period.

This is a bundle of ?glass Fibres? about 12mm diameter and 120mm long, they are tightly bound with a cotton cloth. My guess it is for burnishing or Polishing?

These items are similar to my boring tool but have a long cutting face for side cutting, not end cutting like a drill bit, a reamer perhaps or even a milling cutter ?

Got it in one, scratch brush, unwind a bit of cord as it wears down.

Next lot are mostly DS-bits, the poor man's reamer.

last one includes an edge finder (at left) and maybe a spade drill made from a broken bit for a brace and bit?

1. The long thin one, has a tapered square shank for holding or driving, the working part is 5 sided and very slightly tapered.

2. This item was made between centres and is a work of art, could imagine it would have been the kind of tool to bore my Stuart Turner 10v cylinder.

Some of the other items look like 'D' bits, & what look like spring wire guides for making your own springs… IIRC, you had a mandrel in the chuck, a coil of appropriate piano wire which was fed through the hollow centre along the grove then you had a few calculations to do to set your coil length, set the screw pitch on your lathe gearbox & mad your own springs.

The tapered object could be a broach, the other looks like some form of camlock object ?… just having a guess

The glass fibre item is a comm stick, for cleaning commutators on electric motors. At least, that was what we were issued with them for by the Post Office.

I also used a fibreglass stick for cleaning commutators and slip rings on exchange ringing machines when working for Post Office Telephones between the early '60s and late '90s. They were eventually discontinued because the dust generated when they were used was deemed to be harmful to health. Needless to say they were retained for as long as possible, one chap used his to clean pole faces and armatures on PO 3000 type relays.

Another vote for the glass fibre bundle being a comm. cleaner. When I was an apprentice I spent a few months in an electrical engineering workshop, these were used in preference to emery cloth for cleaning commutators, cannot remember why (embedding?) other than if I had to use emery, use a bit with the "fight taken out of it"! Still have a couple that occasionally get used for cleaning motorcycle dynamo comms.

Sorry, I think I mis-interpreted the picture.

Yes. During my time as an apprentice in the Electrical Maintenance shop I was told that emery embeds itself in the copper comm-bars and carries on doing what emery does best.
