a few extra stuff, Hresvelgr is unmanned, Zelfikar/Baselard is. In the first part, the Frame Arm was identified as Zelfikar with all the boosters on, but later on it loses the parts, making it identify as Baselard. If you look at the plastic model kits of them, the Zelfikar/Baselard is just the standard Baselard kit with Extend Arms 02. But in later kits, Zelfikar appears in: Test Color (similar to the one here), Gust Arrow (GA), and Night Edge (NE) which is the final form of Zelfikar/Baselard
Find it hard to believe but the name suggest otherwise. Yes, it says there Baselard but when i looked at the model kit of these 2 mechs, its actually Zelfikar. Apparently that version is a prototype. Thats why it has Baselard's color scheme...just adding a Blast Shield armor on www.1999.co.jp/eng/m/10311999 (check on this site)
it is technically baselard at it's core. The only thing that makes it zelfikar was the extra armor which was supposedly made to mimic those energy sheilds the hresvelgr had.
