In the Spielberger Panzer IV book there is a side view of the Krupp(?) proposal to put the Schmalturm onto the Panzer IV. Has this been covered in any of the Panzer Tracts series yet?
I'm aware that the turret is covered in the Panther volume 5-4. I'm especially interested in the driver and hull gunners access hatches.
As I'm 'resting' between jobs I've got to watch the cash so can't afford to buy reference stuff hoping it's got what I want in it
On the other hand I've got my stash to keep me occupied
