After getting some parts from Forgebear, we can also confirm it should work well with Henglong upper hull and the turret ring also fits.



Next job is to build up the Flakvierling 38 inside
The lower panel screws on and has threaded metal inserts to help ensure the threads don't strip as they would most likely do in plastic.
A servo sits under the turret to operate the elevation of the guns, soon i hope to be able to test it, but i need to source a Panzer IV upper & lower hull to try it all out.
If someone has a spare upper and lower hull let me know.
The turret includes internal details with ammo racks and seat posts etc. So once all cleaned up and painted, it will look great
Maybe i will look into a Ostwind as a next project.................
