For the M1911 1918, it would be a two-tone magazine like the one on top, without the lanyard loop.
For the RR, I think it would be all blue.

Thanks Jacob

So there will be a lanyard loop on BOTH the magazine and the mainspring housing? Thank you, Ed

No, there will not. The lanyard loop magazine was discontinued before that Colt was made - 1916 if memory serves.
The correct mag. will be two-tone without lanyard loop.
Here's a good outfit that may have some.
