i bought one of these and it arrived the other day with some other parts from sls,it does fit into the spare wheel,the info that came with it suggests you by a fixing kit,and then goes on to tell which kit is right for which model,113 is not listed.my car is a 280 and the wheel lies more or less flat fixed by a threaded bolt with a disk to hold the wheel central and then a handle for gripping,if i got this extended it would do the job nicely as the can has recess for the disk part...but,theres allways a but...,it looks like the tyre cover poper wont fastern down as the handle is to high,could allways change the top of the handle for a large bolt head,but i wont rush in to anything yet.it sort of defeats the object.
the can itself looks very good its metal, a dark gray in colour,with a polished metal flexi hose,clamped to the top, i wouldnt think it would leak.proberbly look more at home strapped to the side of romels staff car though....if you want some close up pics,get in touch.
