The Early Russian Handwriting

I'm going to take a slight tangent and just ask you about your research skills. You're obviously fluent in Russian but can you read documents in Church Slavonic do you know this sort of predecessor tongues of Russian? Well I mean I could make my way through some of it if it was printed but no I'd never really need to use Church Slavonic texts and very few people do and most who do them read them in modern translations. So on the earliest Russian handwriting I've had to deal with is 18th century by an administrator in Orenburg, Russia. This Russian was quite difficult to make out because they tended to write in a sort of beer Socrates as we might call it
