No steel decks. I purchased a number the MRY-SFW kits as you did. Belknap came with a split hull as well.

I believe EV and MRY-SFW share the same print files. I looked at accessories rafts that EV sells and those of MRY-SFW that came with my kits and they are both just shape and form but no detail to the accessories. My next clue was EV’s ASROC launcher. It has to be glued together one canister at a time as does the MRY-SFW models ASROC launcher. They are also in same layout location upon their accessory rafts.

I have learned two lessons. 1st lesson. Stick with the unbranded 3D producers on the evil site. Their models are true to their photos. 2nd lesson if I already have the subject in resin or mold injected and it’s ehh just buy upgrade parts and make it a better looking ehh
