Single end metric spanner set

[powerwagon63]

Found this set at a rummage sale yesterday. Will probably never find the missing bits. Anyone know more?

No idea on them, but I would have picked them up too!

I’ve seen quite a few of those wrenches in the U.K. and some other patterns too, such as ”C” wrenches.

My thoughts are the same as goldtang above. The patterns found suggest that they were supplied with machine tools.

I suspect from the typeface I’ve seen on some that they are of European manufacture. The examples I’ve seen seem to be of very good quality as I can’t ever recall seeing any with noticeable wear or damage.

Very nicely proportioned too.

Interesting!

I've seen similar tools in European motorcycle tool kits, but not as a complete set. You only get a few sizes common on the bike, like 10 and 13mm.

quick Google I did find

the tools you found are similar to the tools that have been supplied with some of the machinery (lathes etc) I have worked on over the years just different or no name

My work-in progress SOE Engineer's wrench collection. Show yours??

I grew up calling these "Engineer's Wrenches". I've come to realize that some here reserve that name for DOE's. If you have time to chime in with pictures of yours, let me know what YOU call them! I grab 'em when I can, unless they're a duplicate of what I've already got. Here's mine...
