JP,

Would it be possible to get a picture of the extreme right side of the label, just cannot read the right end of the label in the one photo.

Thanks,

Brian

i didn’t buy this ctge and let it to my friend because it was too expansive.
Indeed it is 100 times scracer than a Pauly and this one (with the picture) was unknown till now.
Next time I see my friend I will make new pictures.
