This would be the "11X44" configuration where the 11/44 is mounted in a 40 inch top-loading H9642 cabinet ("corp cab").

See http://bitsavers.org/pdf/dec/pdp11/1144/1144_UsersGuide.pdf, Figure 4-5 (page 4-7)

Out of curiosity, is there a manual for this style PDP-11/44 online?  This is the style I have, but I’m pretty sure my manual is for the pull-out enclosure.  

A manual on this enclosure might give some idea on the gas struts.
