Lee Filter Information on the filters

[spassig]

I have some Lee filters.
Does someone know about the information, see screenshot.
10/15.
07/13, GS.
04/14, GS.
I think .9ND and .6ND mean neutral density?

.6ND = 2 stop Neutral Density
.9ND = 3 stop Neutral Density

GS = Graduated Soft - they also do Hard versions as well - it's to do with the degree of feathering in the transition.

Not sure about the numbers - my guess would be month / year of manufacture - e.g. 10 / 15 = October 2015.

Thanks for feedback.

I agree with You.
The filter with date are resin filter?
I can tell the difference between resin filters and glass filters by the sound when I knock on them.
Why do only the resin filters have a date?
Is it due to ageing?
