TZ-3 back window cracked

The external back glass window of my TZ-3 cracked. Everything else works fine. I tried to find a replacement window for this camera but without success. I did find, however, similar windows offered for other, later, models. could you help me to find out which models have the same window? The external dimensions of my window are: 68.7mmX51.0mm ( 2.7"X2.0"). The window has a black frame printed on it which is 2.5mm (or 0.1") wide on three sides and 5.5mm (or 0.22") on one short side. Such windows come often with a fitting frame of double sided adhesive tape .

Thank you in advance.
