I tried to answer the question you asked--the crystal of any NTSC (US TV system) is 14.31818MHz, just like the one you are trying to replace. I would have expected a EuroPlus to be PAL TV system, with a different crystal frequency (see below).
14.31818MHz is typical for machines that are NTSC. For PAL, the crystal typically is 17.73447MHz. Just replace the crystal with another that has the marking 14.31818MHz. Or try to resolder the broken leg if it's possible. Crystals cost something in the order of $1.50, so it's not expensive or hard to get.
My understanding is that the PAL version used a 14.25MHz oscillator. -michael 8-voice music synthesizer using NadaNet networking! Home page: http://members.aol.com/MJMahon/
