I found a later built cut 245 Red Sentry and I see the ID plate must have been continually revised to the current patent dates.

Here is N29473
Check out the string of patent dates.

Also this tag is reverse color scheme with silver text on black.

At what date did this Bowser cut 245 ID tag reverse tag color scheme?
