If he also had a 621, the 7BP7, which uses magnetic deflection and focus, could be made to function in that set... a blue filter could be used to remove the yellow-green long persistence component, leaving a blue image, which might be semi-watchable. Since 7DP4s are fairly scarce, blue is better than nothing.
