That's interesting. I have found only one Indian mcy wrench which was in a box of old wrenches in a second hand store. There are a lot for sale on ebay but prices are a bit high.
Some of the Indian wrenches are just flat stamped, while others are cast like bottom wrench in my photo. Maybe the flat ones aren't as useful and don't hold up well (flat wrenches sometimes spread open when used).
There's a very nice adjustable wrench available in two versions - one of which is made by Manzel - which you, skip, confirmed for me in another post.
Last year I bought a Royal Enfield built Indian Chief - imported after the Springfield Massachusetts factory shut down. I have been watching ebay for Indian wrenches. Mostly not affordable for me. Especially since I don't have a "real" Indian mcy - I like Brit bikes.
