I just noticed the comments above mentioning the 9-inch Lohmann Brothers refractor originally at Parsons College in Fairfield, Iowa. To clarify about the status of that telescope, I've created a new thread in this forum today. I didn't realize until just now that the comments and questions above date to 2015! In any case, I know folks here will be interested in the new thread. Cheers--
