Yep that is a 900m focal length. Sounds liek the finder would be either a 5x24 or 6x30, but I'm not familiar with the scope so not sure. One thing you could try is take the scope to Bintel and see if their 6x30 finders will fit.
When buying a star diagonal for my refractor, I took the scope in and they were happy to let me try the diagonal with my scope before I bought it.
