I haven’t had to occasion to use Gen Mar, but have experienced similar situations with on-line orders. Chillowhee, one of the advertised vendors on this forum makes custom leather items for the Valk. Excellent folks. They recently moved from Oregon to Colorado (better weed in Colorado I guess

), anyway, they had a few hiccups during that transition but made everything right. Fortunately, PayPal is pretty rock-solid regarding issues like this and will refund your money if they can’t get a satisfactory response from your vendor. It just takes time.
Good luck and let us know how it turns out.
