Looking for information on this gravity knife

[Selachii]

I found an interesting gravity knife and wound like to repair its spring. It still works, but the button is loose. I was unable to remove the spring from the button housing and don't want to ruin the original part. I've tried on spare parts, but its like welded in place.
Any idea how to remover it without brute force?

I've also never seen this companies name, do you have any information of it by any chance?

Regards Selachii

This is" kappmesser "either M1956 or M1963 ,they have slight variations between 1st and 2nd models ,look on wehrmacht awards to see the differences and learn more about these interesting gravity knives .
If it has an eagle on the grip it is military Bundeswehr issue and should have some inspection numbers on the trapdoor .Others were made for sale to civilians ,I have seen Anton wingen ,,Eickhorn and WKC examples but never one with this nice Gazelle stamp.
I believe it could be by" Gebruder Krusius "but I am not positive so you may need to dig a little more .
I cannot help with the repair as these were notorious for breaking ,maybe Bill has an idea on repairing these.... if anyone knows it will be him ,and you are in the right place. .

Thanks for sharing it as it is a mark I have never come across on these knives.

Welcome to the forum

P.S
Found this S/A dagger and the company logo etc ,there is a write up of their history if you type in Gebruder solingen knives and do a search .
Hope this helps a bit .

Nor have I ever seen a Gebruder of this type.
If you want to remove the button spring, you have to remove the button by driving out the button pin. Trying to do so otherwise will ruin the spring, and you can't get a new spring in unless the button is removed.

I just received a small ERN zinc plated gravity knife that also needs a spring. The previous owner told me that it went missing one week after he bought it and that was over 50 years ago. Got really lucky that it ended up in a drawer, he told me that it would have gotten thrown away in a couple of days if nobody had bought it.
I will let a machinist make me a few replacement springs and just hope they used identical ones in the bigger gravity knives made by Anton Wingen (Krusius).

Thank you all or the information on the Gebrüder Krusius knife.
