I had the pleasure of stopping by Scott's shop the other day and spending the day with him, checking out his rockets, kits, r/c airplanes and nerding out about planes and rockets in general. I had brought him one of my R/C glider kits and he offered something to me. Back in the corner was a 4" scud missile. He showed me on his laser cutting files how it went together, it's set up for dual deploy with an altimeter/camera bay in the upper half. I decided that I did not want to use the camera/dual deploy but did want altimeter deployment for the main and not use motor ejection. I have a small self contained 38mm altimeter bay that holds my altimeter and it is used in all my rockets. I either velcro it in place in my large foam rockets or screw it against the inside of the tube in my larger highpower rockets. The small bay vents through a hole to the outside of the rocket. We adjusted some of the lengths of the tubes, where the bulkheads sit and he fired up the laser cutter and cut out the parts. The slotting of the tube using the laser was really fast and neat. Normally I scratch build and it's been a long time since I built from a highpower kit, but sometimes the neat details and cone shapes that makers provide make it so much easier to do something different.
This kit didn't get many orders so he pulled it from the online store but it has some neat details and I think is a great missile that isn't modeled very often. A nice change from Pershing 1A's, Patriots, etc. The nose cone is 3-d printed and you glue a short coupler inside for a shoulder. The fin unit is a tab and slot contraption that locks things together and holds things in alignment. It includes lots of little details, laser cut paper hatches, balsa details for the fins, fin steering vanes and supports, and conduits. These don't really show in pictures if you paint it standard dark or OD, so I may choose a dessert sand type of scheme with a russion red star marking like the old Estes kit that may help to show off the details.
The kit comes with a 38mm mount and some neat blind nuts and clips for retention but I decided I will most likely run 29mm via an aeropack adapter for G-80, H135 and I205 motors for a range from 800-2500' altitudes depending on the day, using a chute in a deployment bag, kevlar recovery cord and quick links, and nomex chute protectors under the deployment bag. The deployment charge ematch will go through a hole in the upper bulkhead down to below the chute protectors for single deployment. Scott provided a nice tube/centering ring 29mm adapter but I already had the aeropack and so I decided to use that. I also chose to use a 38mm aeropack retainer as I had that too and it's very simple, and no tools needed. I attached the cone to the altimeter section using four stainless screws instead of the plastic rivets, just a personal choice.
Here is where I'm at after today's efforts. If this interests you ping Scott Binder, I'm sure he can kit one up for you. I modified the ORK file Scott sent me to match my internals and weight so far, this will be adjusted as I progreess. I need to add the steering fin supports, conduits, paper hatches, external fillets, retainer and then fill/sand and paint. Most scuds don't have markings so no decals were included.
Photos show the cone, payload section, full assembly, fin can which is assembled then pushed into the pre-slotted main tube, and all the little parts after cleanup and adding bevels to the conduits and balsa fin details. The fins even have laser cut score marks very light to help in locating some of the details.

and then sand using a dowell and sandpaper attached till it would slide in and out without problem. Scott said that he had a bad batch of tubes, and to be fair we realized at 7am the next day we forgot to cut the motor tube so he grabbed a piece and cut it, he said he normally checks these for fit on a motor before shipping so I'll let that one slide
