I'm glad it was resolved and will state here to any who read the thread that I have also messaged the buyers of the other items, asking them to check and confirm originality of ALL pieces. Have already received reply that one is fine, awaiting others that are either yet to a) read PM sent or b) still awaiting delivery of item(s).
Although I buy on here more than I sell, ANY problems I will ALWAYS try and sort it out for the buyer ASAP. Have had nothing but positive dealings with quite a few guys on here already and hope for more in the future. Even the buyer who unfortunately received a repro item recently, has had a positive transaction previously, when I bought from him, resulting in positive feedback from both sides.
And finally, just to add - I know I need to pay more attention to the repro weapons - this one clearly fooled me...but as I said and will say again, I am sorry for any inconveneince that was caused and hope if ever any issues arise in the future, they can be resolved in a more amicable manner. Just isn't in my character to do it any other way and this forum is full of friendly folk.
