Even More Diaclone and G1 Concept Art – Fortress X, Hun-Gurrr, Transforming Books, and More!

More Diaclone and early G1 concept art has been discovered once again via Twitter user @miiakira2017.
Since our previously reported story and its followup, a new image has been posted featuring Diaclone Lambor and a mobile command base, as well as a pair of new images of transforming Autobot and Decepticon books!
Also, thanks to Allspark member Spark trudging through some questionable content on the user’s twitter feed we have images of concept art of what would become G1 Hun-Gurrr as well as concept artwork of Diaclone Fortress Robot X!
Check out these great images mirrored below!
