This reminds me of the days, probably now the best part of 50 years ago, when William Evans still kept rifles for sale in a rack backing on to the side window of the shop (we were less security conscious in those days).

I was particularly taken by a brace of cute little 6.5 MS carbines. As they were too short to stand safely in the rack by themselves they each had a Parker-Hale cleaning rod inserted into the muzzle to hold them in place.
