Not quite sure what all that was about ... kinda strange, for sure. Hopefully the parties will apologize to you for that less than congenial welcome at some time in the near future.
Welcome to the forum, Karlito!
As far as whether the cymbal in question is a ride or a crash ... weight would ultimately determine that. If it is heavy and pingy - ride. If it is medium weight and gives a nice woody ride pattern while still opening up a bit - crash/ride. If it is washy and wants to stay open - crash. There's not really a science to it. Even the cymbals marked "ride" are often used as crashes ... and vice versa. We're drummers. We make it work.
The drill holes were most likely for rivets. These are made from various types of metal (brass, steel, aluminum, small cats, an occasional underripe gooseberry, very loud worms, etc). They are installed in the drill holes and vibrate when the cymbal is struck. It adds a bit of white noise (SIZZLE) to the natural tone of the cymbal. My guess: this was originally a nice old sizzle ride. It has a wonderful patina formed and would be a sweet addition to any jazz-lovers setup.
Congrats on the beautiful cymbal.
