I checked and double checked and I do have 20 Central Powers kits. My unbuilt ones are Roland DVId, Pfalz DXII, HB W29 and Albatros DI, II.
The Roland is next after a WNW Junkers D.I which is nearing completion. The Roland is my oldest unbuilt Pegasus kit, before the white box. It is the one in the plastic bag.
I thank everyone for their comments on the collection. It represents about 38 years of building. I wanted a large collection. Be careful what you wish for. The collection is now over 250 models. I figure I can build about another 10 before I max out my shelf space. After that, no idea.
