in asking that question I infer that perhaps you are having difficulty getting in touch with him?
I would be very surprised if he is not still in business. However, getting in contact with Kirk can at times be very frustratingly difficult.
he is a one-man shop with a business and a family to take care of, so his time is limited.
his products rightly have a reputation for excellence, I would encourage you to continue to attempt to contact him.
