I've developed a Low-Level bombsight for TR's B-25 series (...skip-bombs? ...we don need no stinkin' skip-bombs...)
It is a 200mph/0.62X zoom (as opposed to the Std. bombsight w/ a 200mph/1.0X zoom) which is the 0.64 zoom ACM std. zoom from the cockpit. (don't know why it indicates 0.62, ...but it does.)
The water-mark doubles as an "on-speed" indicator, ...due to the pitch change through the +\- 200mph speed range.
Set EL, ...Set speed, ...drop at the elevation hash.
Will hit w/ singles, ...or sticks...
