after you click onto this page then look for the 15cm sFH or 21cm MRS type you are interested in, to the right you will see its limber. If you click onto these small images it will open into a full web page on the subject. I have not yet put in the 21cm Limber drawings or photos but I do have the barrel wagons. However, you can see the limber in some of the photos of the barrel wagon on the 21cm MRS 1910 L/12. I am not completely sure, but I think the barrel wagon limber and the MRS limber are the same.
This section of the web site covers a number of German Artillery Related topics. These are only pieces within the collection in color photos. Again, just click onto the images to open the web page on the topic. The saddles and harnessing that are used in conjuction with all Foot Artillery (15cm and 21cm) are covered in the Transportation section. Note that the German Field Artillery used a completely different saddle and harness. Also, the saddles and harnessing used in WW2 for these howitzers and mortars are within the section.
