I will post references tomorrow but Späte's recollection of it being armed with 20mm doesn't match up with other data. I need permission before I post and am waiting on an email.
RLM 23 is less orange and more a red..
RGB = 158/21/25 or hex = 9E1519
As I said at least in your images above they look more orange then red to me anyway...
YMMV
