The grip looks typical Pack light brown
and fittings same.Got my upper guard off with same caster marking.Can,t get the rest off
and wont try.But the clincher is the etch.
Like Gailen says,I think you should try
pics square on to the etch and Pack mark
for a better appreciation.Sorry to bug you but
would be worth it for broader opinion.JMO.
