In Reply to: bore size of a Barlow F? posted by Brendan on June 23, 2003 at 21:14:52:
The Barlow F's were actually a series of 14 none compensating prototypes made by Besson (pre B&H)for Harry Barlow who was Tuba Player in the Halle Orchestra from 1895 till about 1924. They were progressively larger as the project progressed, I dont know if the bore through the valves was any different in the early models, but the body was considerably smaller than 10 through 14. The bore of these were 17mm for 1-3 and 18mm for 4&5. The valves were metric because they were made by Brevett in Belgium.
Just for interest, Philip Catalinet DID NOT use a 'Barlow' to record the VW, it was the standard B&H compensating F Available at the time, an instrument that B&H in their infinate wisdom stopped producing in the early 60's.
