I came across a nice set of metric Thorsen combo wrenches in March. Someone said they went to 19mm, so, I've been on the lookout.
Found a 22mm today (but it didn't look good, so I left it) and an Action 17mm. Same 4 digit as the Thorsen's (10XX), with an added "A". A for Action I guess? But it had minimal chrome peel, nice looking. So, one down, and the quest continues!
