Just bumping this up. I detect a distinct lack of interest in these now, maybe I might well stop making them, as really I make very little out of these when you factor in time and material cost, maybe we have reached saturation point.
I have calculated that I have constructed well over 300 since I first started over 12 years ago, now from memory.
In addition to the above, I have noticed in recent times when I respond to a request, it is quite common now for people to just disappear and not even acknowledge my correspondence, which I find rather frustrating and to be honest quite rude.
