Enough of reissues.....

[rattle can man]

older subjects are mainly the kits that I am interested in, but something that hasn't been re-released  in a long time. If a re-release is done with only decal changes from a kit re-released 5 years ago, I probably won't be buying.

Some of these ancient kits went dormant for good reasons. The molds are worn or missing parts would be my worst case scenario. 

Any tool drawings, nothing stored on CAD, could be missing or incomplete. Trial runs would have to be made to sort them out.

Master models at one point existed for many kits.

Mold repair is largely a lost art. I have seen parts trees where repairs have been made in the past. 

We are in the digital age. Things like 3D scanning exist to help translate the model geometry to a CAD format. Processes like wire EDM make molds less labor intensive.

All of us would like to see reissued kits made with fresh tooling. Look at the '65 Chevelle AWB as an example. That appears to have new tooling, the body is a lot crisper. The parts trees are laid out a lot better.

It all boils down to profit and ROI. New tooling is not cheap and thousands of kits have to be sold. I have always wondered how many molds exist for any one release.
