Hektor 7.3cm ƒ1.9 - minimum focus distance

[menos]

I recently bought a Hektor version 2, made in 1932.

I went through a CLA of the lens, described in this thread:

http://www.rangefinderforum.com/forums/showthread.php?p=1706038#post1706038

Through the work, I have found, that my sample of the Hektor 7.3cm does not focus to 1.5 meter, but can actually be focussed to 1m !

Here is a excerpt from the CLA thread:

My sample does have 1.5m as shortest focus distance on the nickle distance scale, but it actually can focus to about 1m !!!

This actually confused me quite a bit, when I collimated the lens on the M9 against a reference.

When focussing beyond 1.5m (closer) the Hektor gradually shifts focus to the front, resulting in a healthy front focus of about 2-3 cm @ 1m (not exactly measured, but estimated)!

I have been mislead by this behavior initially, but found out after intensive testing at different focus distances.
My Hektor focusses perfectly sharp, wide open from 1.5m to ∞.
It can be used up close to 1m, when compensating, leaning to the front (making the Hektor actually focussing closer than 1m ).

Is this a standard behavior of the Hektor?

What is the minimum focus distance of your Hektor 7.3m ?
