Featured Any ideas what this old tool might be?

Hi
I recently won a nice old 18th-century pocketwatch on an auction, and as a bonus I also got a strange metal tube with tools inside. But I have no idea whatsoever what it might be...
The tube is about 10 cm long and opens up to reveal a set of tools: knife, ruler, pincer, pen? and some other things. There are also lenses on each end of the tube, and when the two lids are opened it seems to work as some kind of crude monocular adjustable by making the tube longer and shorter. The center hole in the tube is free from tools and runs the entire length between the lenses.

If anyone has any suggestions what it might I´d be very thankful. Perhaps an old travelling-kit for the well-shaved spy...
Sorry for my awful mobile-phone-pictures...

Best Regards
Matthias

 

Itlooks as if it might be useful for doing field mapmaking, surveying or chart making.

 

I swear that looks like a mini telescope ! That is so cool,I especially love the knife.

 

looks more like a bug collecting kit to me

 

Fascinating!!!!!!!

 

Ya...but the knife is throwing me off....& I haven't found anything close so far...

 

2 'period' uses for a knife apart from from general cutting are trimming and shaping quills to write with and erasing mistakes. (By scraping off the surface, not stabbing disorderly crewmen)

 

Judging by what appears to be a drafting pen nib, dividers and straight edges with adjustable angles, pen knife, I should thing some sort of drafting/drawing/map making/charting/etc.

 

yes, but there's already a pen there !
But no ink well....so maybe the knife was used to draw blood ...????....

 

A pen knife was also used to sharpen a drawing pencil "in the field" and if used for drafting/surveying a bottle if India ink would have been used in place of a traditional ink well.

 

this is an old map making kit from kerr

 

I have a Bruning set basically the same (case and all) - but I refuse to call it old - it was NEW when I got it for school................

 

Thank you all for your help in figuring out what it might be!
I´ll investigate further in the chart/map-making area. I feel that I should at least give you some better pictures than the ones I took yesterday with my phone...

 

Does the tube act as a telescope, or can it be used as a microscope? If you have a Pinterest account, you can look up scientific etuis.

Don't know what you paid for the pocket watch, but I bet this would go a good way to offsetting that cost.

 

Much thanks to the helpful members of this forum, I think I have finally managed to google my way to the solution
It seems to be identical to his thing sold on Bonhams (although that one was in better outer condition and in gold...). They also sold one in silver similar to mine but the gold one seems to be the same proportions and decorations.
The cheaper silver one sold for 10x as much as I gave for the whole lot, so as much as I liked the watch, I have to name this the true prize of the auction.
Not a bad bonus at all I have to say

Thanks to all of you again for your help with this mystery!

A rare gold mounted spy-glass nécessaire, English, third quarter of the 18th century, with gold mounted fittings and floral swag decoration, sliding cover to eyepiece and objective, green stained fishskin cover, opening to fitted interior with penknife, pencil, scissors, bodkin, tweezers and ivory leaf, 4 1/4in (11cm) long

 

That's closer than anything I've yet to find...........

back to the hunt !!
