Dark green cloak in 4502/ 6400

[GrahamB]

PlaymoDB shows the Night Watchman in both set 4502 and 6400 as having a 'very dark green' cloak, full-length.
I bought an unopened copy of 4502 recently and this has a grey cloak.

The very dark green cloak does exist, so can anyone answer me the following?

Was a dark green cloak only included in the very early issues of set 4502?*
Was 6400 issued (in June 2014) with a dark green cloak?
Is there some other set with a dark green cloak?

*My MISB set includes a mini catalogue dated 03.94, one month after the release of the first 4502s, so it's later than those; the first 4502s had perforated boxes with three pink corners on the front, mine has the later unperforated box with four pink corners. See here

I had the original 4502 with the perforated box and the cloak was grey, I've also had the 6400 Direct Service one and that was grey as well.

I have two of the original night watch from the special, and they both have the same grey cloak. Must be a playmoDB mistake.

Is there some other set with a dark green cloak?

Are you only interested in that style?

There is a darker green cape (with a peg) in Set 5831.
