air raid siren housing

just a housing for the thing this is a remix of and room for a motor on th back, have not designed th centre bit .yet but will someday, use two of the insides from the orignal, one mirrored and one not mirrored, place back to back and add motor;. with the tube i have not done yet unless some one else wants to do it and add to this.

i would suggest scaling it up, its in scale with the inside parts on the source page
