No experience with the collapsible 90 Elmar, but with the collapsible 50 Summicron, the end of the lens contacted the light baffle very cose to the light meter aperture/lens, so I did not use it collapsed.
Not sure if this helps but the collapsible 90/4 Elmar M-mount, and 50/2,8 Elmar M-mount and the 50/2 Summitar (LTM but with M adapter) all collapse and fit fine in my R3A. In regards to the eBay one mentioned above, that's the one I have. Great lens! Example here:
