If you need assistance posting photographs of your Luger, you can send them to
lugerforum@gmail.com and I will post them for you. Please take clear focus photographs of both sides, the top and the front of the frame, and under the barrel.
Let me add my own Welcome to the Lugerforum.
Please also photograph the damage to the magazine. Perhaps all you need is a part, rather than an entire magazine. I do not know the laws regarding sending firearms parts to Thailand... but often, the sending of repair parts is not a problem.
