Very interesting, I already listed them on TAW.
Both known 1998 series are probably the most common around and we are not far from knowing the complete sets. Luckily, both large and small lions are now added.
2002 has the most interesting series, I guess, they use to be marked with 1310-P# but I believe your figure is smaller and has no product number marked on it.
2008 figure is a completely unknown design for me, this is the period when Schleich already dominated this niche of market and most companies tended to make figures compatible with the German company.
Which ones are hollow?
