I ordered two of them, a 20 and a 28. The gunsmith that I used to polish and assemble them took agreed to do about 15 of them for different customers. This was over two years ago, and I haven't received mine back yet. In fairness to him the metal parts were really "in the rough", not "in the white", and I think the work required was much more than he anticipated.
I have enough other projects going on that I can wait another year or what ever it takes.
If you buy one of the kits, it's essential that you have someone with the time and ability to prepare and assemble the parts, if you can't do it yourself. On my kits the parts were so rough and so much hand fitting needed to be done that I imagine it was almost like building a gun from scratch, except for the receiver and barrels, and I don't think the barrels were fully bored out to the proper diameter.
