items from an old (1950's) toolbox

[OSAO]

A while back I purchased a toolbox at an estate sale, it looks to have been used by an aircraft mechanic / machinist. The box was full of tools and items that end up in a working box (parts, screw, etc) and there are a few items that I can't quite figure out.

One reoccuring theme with some of the tools: a drive that is a little smaller than 3/8", and sometimes appears female where it looks like it would typically be male. Some of these tools are marked with a size that does not look like the actual working size of the tool. There is also a reversed "hex" (not square) drive that appears on many of the sockets.

Does any of this ring a bell?

I will post some pics later today..

Was this estate sale anywhere around area 51?

Ok, it looks like the original owner took a couple of long aircraft cylinder base sockets, and cut them down. The Y905 was neatly grafted onto a bigger socket. The Y903 was not as neatly attached to a female 3/8" drive. The "smaller than 3/8" drive is pictured next to the normal 3/8 drive (for comparison), as well as a couple of what look like 9/16" box end with 3" male 3/8" drive (which could be driven with the 1/2 female to 3/8 female adapter).

Also, what was the Bonney B75 plier used for? Some kind of rivet work?

I will go through the contnets of the box and post some of the more interesting items, soon..

Sorry for the huge pics, I have a new camera and have not figured out how to take smaller pics (without having to reduce them in post production)

11/32 drice tools, hex drive sockets, and more..

The pliers were from a different batch of tools, and I feel a little stupid for not knowing that. I have some other pliers with a similar head, I should have put it together..

Anyway, I went through and took some pics today. I have searched for info on 11/32" (smaller than 3/8") drive tools, hex drive sockets, and couldnt find any info.

Here is the hex socket set:

Here is an 11/32" extention, and some specialty sockets:

Another socket, along with the plug that it drives:

Not sure what this (the tool, not the ruler) is:

Not sure what this is:

Pullers / removers that I would probably never have a use for (but would be interested to know if anyone knows what they were used for):

I am guessing that the "NAS" (Naval Air Station?) and other stamps were used on parts repair tags?

The box also had lots of sockets, wrenches, punches, taps, dies.. Here are a couple of Plomb wrenches:

I'd say your right about the NAS stuff. The tools marked PWA are Pratt Whitney Aircraft.

Another socket, along with the plug that it drives:

1st pic: They're for tightening the ends of push rod tubes on radials

2nd pic: Appears to be similar to a plug from the end of the rocker shaft in a radial engine, but a design I haven't seen before.

NAS is National Aerospace Standard.

Thanks for the replies. There are a fair amount of tools that have been repurposed / hacked together to become another tool. A few of them were originally Pratt Whitney tools, or at least their SnapOn part number came up on PWA websites..

NAS, National Aerospace makes sense, since other items in the box seem to be from aircraft companies that would not have been military / Navy.
