Let's build an Indian kit, sell it, and split the proceeds!
Here's my contribution..., marked with a circle-M (Moore Drop Forgings?) on the flip side.
UNAIU,
First off, very interesting wrench. Never seen one before. As an Ohio boy, and a tool collector, I won't waste your time telling you about Vlchek, cuz it's obvious you know your chit and were asking about the wrench, in particular. But, I will recommend you read Frank Vlchek's biography. I skimmed it once and I don't recall anything about motorcycle kits, but it might be there and I missed it.
Secondly, I'm curious if Ricky Joe's statement is a theory (same exact wrench as the Hendee made Indian marked wrench, so must be an early version), or if he has some reference that shows that Vlchek supplied tools to early Indian toolkits. I have never heard that connection (Vlchek->Indian) before and it seems too huge to escape notice all these years.
The thing is, I'm not sure there's anything uniquely Indian about primitive DBE hex spanners with those opening sizes for motorcycles. So, it could have been made for any mfgr. Also, it might not have been made for any motorcycle mfgr. It might have been made for an auto store (e.g., Western, etc) selling common service tools to motorcycle enthusiasts. The plurality of the marking ("MOTORCYCLE
S WRENCH") is interesting in that context.
I could be wrong. Maybe Ricky Joe could tell us his source. It would be pretty cool to discover something new about Vlchek.
