I picked up my Corbin from Kimpex back in 2001, I dont think they carry the line anymore.
Seeing your from Van. I would check out Corbin dealers in Washington State & do a weekend get away. Another alternative would be if you know someone who has a mailbox in WA have it mailed to them & then spend the weekend.
There are also places that will rent you a mailbox for a nominal fee, you would have to check it out, I know of one here in Ont. but not in BC.
I have also seen brand new ones available on KIIJII for sale.Dont know what model your on or year but if I hear of one Id most certainly let ya know.
