I don't think he was a member here. I'm pretty sure he was a WWI collector who was trying to help us SW geeks out and made copies of his grenade available.
I bought one of those last summer... he told me I got the last one he had. He might not be making them anymore with so many other replicas availble? He replied to my email I sent him from his web site. I say keep trying.
Good luck.
