Thanks to all and a valid observation by DadsTools. Fortunately I'm not a collector in the sense of having complete sets, more a complete range of misfit wrenches. Trouble is, I've gathered enough versions of each that I try to grab a different wrench each time I need a particular size until I've cycled through them and then start over. Not sure of the clinical definition for that, but it's probably not good. This one will be in the user rotation at any rate.
Thanks again,
John
Don't know what the clinical term for that is either, but it's rather benign when talking about tools. Medically, a mental state is only considered a 'disease' or a 'disorder' or 'condition' or 'syndrome' or 'addiction' when it has adverse life-altering consequences. Some guys do this with women--now that could have life-altering consequences. OCD is only a disorder when it adversely affects one's life, otherwise it's completely harmless. And I'm sure it's not an addiction because you can stop this anytime you want. Right?

I must confess that, not being that much of a collector myself, I tend to look at all vintage items regardless to the type in relation to monetary value. I find the excitement in the find, but then need to pass them on to someone else and make some money for my efforts. Yes, I have a very small collection of tools and fishing tackle that are of a historical interest to me personally, some having very little monetary value in collectors' circles. But beyond that, to simply keep buying things without the intent to resell them just because they're old or odd drifts into the "H" word, at least for me. If you watch cable TV, there's a number of programs illustrating the results of such habits. I also concern myself with my wife who is 11 years younger than I as to what she would be confronted with if I passed leaving her with a hoard she knows nothing about. So I have fun getting them, take a moment to delight in what I found, then move them along. Just sayin'.
I like that you mentioned about your mish-mash user sets. I have found value in putting together mixed-brand sets of USA wrenches to sell cheap for a backup set, a starter set or perhaps to have a spare in the truck or the barn. I find that these oddballs have more value together than trying to piece them out individually.
Anyway, hope someone in here has more info on your ROCO wrench.
