dear Penangsang II
Perhaps, to elude any dispute, simply Luks 3. It is very hard to give opinion based on limited and small pictures. Even I still have high curiosity that the steel of gonjo, lion and main blade are different. If they are different, imho, the discussion should end for this topic and move to other topic: dhapur owah-owahan (re-engineering shape

)
According to luks shape, there are several names for luks 3 depended on details. So long I dont have opportunity to open keris books. Perhaps, any kerislover can help us to scan and to upload e.g. Ensiklopedi Keris especially where luks 3 discussed in.
Today in Jawa Lunar Calendar is Suro (the first month). If around 10 Suro this year there is extraordinary moment in Jakarta, especially in Jakarta the capital city of Indonesia and in Solo (which some people claim as spiritual center of Nusantara), the dowry price of keris luks 3 will rise because Lots of people will try to find one or more for their lucks. What kind of extraordinary moment? Lets just watch on Indonesian TV.
Rule of the game in Indonesian today keris world:
if the demand increases, the dowry price increases too.
if the supply can not fulfill the demand, there will be re-engineered luks 3
It is "normal"
Moreover, I dont say that is fake
