I'm looking to buy some shares of Renk, a European company that builds transmissions for tanks. However, there's 2 stocks with identical names, Renk Group AG, but slightly different symbols and prices, and different locations. There's R3NK, and then there's RENK.
[R3NK](https://www.marketwatch.com/investing/stock/r3nk?countrycode=xe), location as Germany:Xetra, and price as 38.04 euros
[RENK](https://www.marketwatch.com/investing/stock/renk?countrycode=at), location as Austria: Vienna, and price as 38.26 euros
Why are there two of them, and which does it make sense to get?
