Machinist Tool IDs... please

[BuddyC01]

'evening....
I picked up a nice, old Kennedy 520 Machinist Chest recently. Actually, picked up is not too accurate, it weighed a ton.
Below are a couple of collections from the tool chest that I can't identify. Hoping a machinist oriented garage person here can help me ID....

TIA

1 2 3 blocks
looks like custom drill guides

1st Pic are 1-2-3 Blocks as pi guy observed above (check dimensions for why they're called 1-2-3). 2nd Pic looks like a set of "lightened" parallels along with some drill jigs or drill jig components.

What are the two strips with the holes made of. If it is brass or bronze they look like the ball cages from a Cincinnatti tool and cutter grinder with the ball roll table.

Those feel more like aluminum and where the bare metal shows through it is silvery. Not sure if they go with the other parts but they were in the same drawer with them.

The inserts on the "drill jigs" are marked for size, 1, 3/4, 1/2...... A couple have an "A" with a lightening bolt going through it side to side. Another is 1/2 G S93

Thanks PI Guy & BSA

Look your ID numbers here; http://www.ucc-udb.com/UDBConvBUSHINGS-PART1-pg01-12.pdf

Drill bushings were/are used in jigs to transfer holes to parts is specific patterns or locations. Those 123 blocks also look shop made and could be specific to setting up a specific part to be machined. Many an old production machinist had these types of tools to set up repeat jobs.

no neat sig line

Yep, 1x2x3 inch blocks.. and drill jigs with hardened steel drill bushings.. probably for specific drilling jobs for production...

Sounded good till you got to the "specific" part. Understandable. Came from a North American Aviation/Boeing machinist kit. I could see it especially on the 1-2-3 blocks.

Thanks for the info!

Yes 1-2-3 blocks, shop made.
Yes long thin parallels but likely made for specific purpose.

The other things don't really look like drilling guides.
The black oxide finish indicates are more ongoing application.
Some of the bushings, (and the accompanying pins), suggest locating purposes.
Possibly for drilling or possibly for some gaging or alignment or set-up or assembly purposes.

Like a great many things found in a toolmaker's or machinist's box, you just had to be there to know the exact use. So much in industry is specialized. We will most likely never know.

I have picked up two machinist boxes over the last few years. I am more interested in the custom and job specific items. Or the tooling they have made. This stuff I find useful sometimes in present form or a idea generator where it is reformed into an other use.
Often you will find non machinist putting together a box of stuff he has collected and trying to sell it as a former machinist tool collection. It will have the tools laid out like an automotive box.
Every real machinist box I have seen is packed with custom **** special screws and a whole pile of oddball stuff.
But there are fewer and fewer real machinists here on LI

This chest had quite a few small items. Some good stuff. Good deal for what it cost me, except for the bad back for a week. A few years ago I picked up a really cool Kennedy Kits chest that belonged to a watch/clock smith/machinist... never quite figure out just what but it really had some cool pieces in it. I love treasure chests. Keeps me busy for a while

I had the same experience.. purchased a small two drawer tool box at an estate auction of a guy down the block from my home in South Bend.. Apparently the guy worked at the Lathe Works.. Several items in it were specialty for repairing lathes, and it is now my indicator tool box...
