When I arrived at the factory I asked for a conference with Mr Rothe, the factory leader, about the price for repair of 65 rangefinders.
Mr Rothe stated he was only a mechanic, and would take no responsability for neither optical nor economical decisions.
I therefore asked if he would call a representative in Stockholm.
Mr. paul arrived from Stockholm on oct. 2nd.
A discussion followed on the issue of repairs neccessary on our rangefinders.
After a dispute, where I stated that our oldest rangefinders were only 6 years old, the company acknowledged their responsability of the repairs, and as I asked for the price to be found before I left, a letter were sent to Zeiss in Jena regarding this.
The letter describes the real relationship between Zeiss and Nordiska Instrument Aktiebolaget, so I have been asked to handle the copy I enclose, with discretion..
(Here is a long description on details of faulty rangefinders, and constructive details.)
During my visit, I got the impression, that the factory possess a lot of experience.
But the skill and the accuracy is not bigger and in some cases even less than what is required at the army optical shop in Copenhagen.
The productivity at Bofors is decidedly less than in Copenhagen, which compared with the higher factory percentage ( 200% against 50%, sorry, I still don´t know what this means)
makes the repairs at Bofors more expensive than in Copenhagen.
These prices is incremented with the fairly high shipping costs and the price of appropriate crates for the instruments.
As an example, we calculate the installation of an ocular prism in Copenhagen at 12 hour, at Bofors it is calculated to 26 hours of work.
There is every reason to free us from repairs done at Bofors, and I feel certain, that we can do this in Copenhagen in the future.
It is my impression that our Chief of shop, Lembcke has sufficient skill and knowledge to perform this in Copenhagen.
(here follows another section with details of instruments used for work at Bofors)
I mention one detail, that was unknown to me:
Whe we talk optical faults, I like to mention pressure in optical parts. If glas element are secured too tightly on their bases, this can cause an paralactic fault. This fault cannot be adjusted. The only feasible way is to disassemble, and then reinstall the component.
This has mainly to do with prisms.
(Does anyone know what this is.?)
The letter mentioned from Bofors to Jena has not been found.

If you mount prisms too tightly, using a clamp or screwing them to a base, you can put stress in the glass that changes polarized light.
'Paralactic fault' seems to mean misalignment, which might mean that the prisms were screwed tightly & torqued into misalignmend.
Thanks for the very interesting translations, Peter
