Device to calculate direction and distance for infantry weapons. Works out to range 4600 meters and operates with direction in mils (/6400). Very useful for calculating defensive lines of fire on maps, as well as calculate individual own weapons locations for maps.
I have one with production code caj.

This seems to have two direction indicators linked. Or does the photo show two devices. How exactly is it used?

[Janef]

Everything on the photo is linked together, with two base plates allowing for direction and tree base lineals.
It is a triangle calculator that incorporates the Pythagorean theorem and the Sine Rule.
Max base lenght is 3560 meters-

Thank you very much JEF

[Carl Schwamberger]

So, the base plates (circular part?) represent weapon position, observation position, target, or other known point? Is the device to be used on a map or chart table, or independently?

Thanks

Does anyone have pictures of a Lang Basis Gerät M42H or a Lang Basis Kleingerät C/36?

Here is all my search turned up. Perhaps this: http://www.kystfort.com/forum/viewtopic.php?f=18&t=930
forum will lead to something.

There are no photos in that particular thread, but you'll find photos in other topics of the forum (check those covering MKB Trondenes and the firecontrol-exibition at Oscarsborg). I have several photos myself, but I'm not sure if they are useful.

Note the links to the US Army intel reports in the last post there.

It's the same links as I posted above.
Many of those links are dead though, as I have removed the files, but feel free to ask for a copy if needed.

Hi Natter!

Is it possible for you to somehow send the US Army Intel reports?

Best regards, Peter

IIRC German arty observers had optical rangefinders, hence devices like the one shown. UK used a similar device pre-1914, but quickly concluded simplicity was better, ie fast procedures and rounds on the ground.

Here some pictures of LBG of Batterie Rozenburg.
It is now in the collection of the Nederlands Militair Museum in Soesterberg, i believe not on show but stocked away.
The pictures come from the old Kustverdedigingsmuseum Hoek van Holland.

Small update to this old message: This very LBK is on display again in the S414 of the Atlantikwall Museum Noordwijk (https://atlantikwall.nl/)! It has been beautifully restored by Historic Engineering (http://www.historicengineering.com/)

Hello,

In the context of M.K.B. :
I miss some information to understand the process. As the "time of flight" depends on the the corrections on azimut and range, and that corrections also depends on the time of flight, I guess one variable have to be manly decided and fixed to work on the others. I guess it is the future flight time ? Correct me if I'm wrong, here is a sketch to clearer understand my questions.

I keep in memory that in the H.K.B. context, suited with poorest set of equipements, they choose a "future distance" that will be reached taking into account the time of flight and the time of gun preparation (loading + aiming).

Best regards

I know this is an old message, but I still wanted to respond.
This former Battery Rosenburg equipment is now fully restored and on display in the Atlantikwall Museum in Noordwijk, Netherlands

Thanks for that. This thread is to good to remain inactive

What I found interesting is that the American report on heavy coastal batteries mentions that the German equipment was outdated and not of any use to modern American fire control. Was this American chauvinism or was the German equipment indeed outdated, over complicated and not useful anymore?
