*HP represents the manufacturers HP model number. Since British Seagulls are rated in foot-pounds the actual horsepower rating may not be entirely accurate to the numbers listed. (33 foot pounds = 1 HP) Sealed box British Seagulls can be recognised by an extra screw in the gearbox casing just above the top gearbox cap screw. This screw secures the bearing assembly.
