I wish I could answer this question. The production has had a few snaqs, I'm just in the loop to know what the snags are, or were. I did the CAD work, & turned everything over to Ron to produce. I wish I could be of more help. I have one which is in my avatar, & Ron has 2 that are completed. Other that that, anyothers that I know of (3 kits) are in Japan.
