The offical designation was probably something like: 18.5cm Versuchshaubitze M17 - so few were built they were hardly anything than a historical footnote. Unlike the pre-war experimental howitzers none seem to have survived.

By the way, you'll find more pictures of this rare howitzer here:

Since 18.5 cm is a non-standard caliber, it could have been a relined 15.5 cm or 17 cm tube, dedicated specifically to this research program ("Versuchhubitze"), possibly to try a new recoil system.
