Were any of the 19 Jewel 60 Hour Type 3 Bunn's factory cased?

Thanks to All

None of the 19J Bunn's were cased at the factory. The Type III's referred to were marked "SIXTY HOUR" on the train bridge. Their serial number range were 4,780,001-4,839,000 and were produced in three runs in 1926 with 1700 TOTAL PRODUCTION .
