Here's a nice, very old laser that should live on a bookshelf. A pre-1975 Spectra-Physics model 155 He-Ne. No shutter, key, or interlock connector, and it looks like it has all of its original feet. Remove the inventory sticker, give it a soapy water sponge bath (don't forget the cord and plug!) carefully avoiding the paper warning tags (which can be stuck back down with a bit of epoxy), and this classic laser will be ready for display.
