It sounds like the horn was modified or had an upright bell substituted.
The model number and a second number were usually stamped on the connecting rings of the bell and bell collar, with the second number used to identifiy which bell goes with which body when several horns were purchased by schools and bands. The serial number is usually found stamped on the second valve body.
The Conn 20J, 22J, 24J, and 26J tubas normally are bell-front with 24" bells.
Add one to each model number for upright bells. All are BBb large bore.
Conn 20/21J have 3 top valves, leadpipe on rightside facing horn from front
Conn 22/23J have 3 front valves, leadpipe on leftside facing horn from front
Conn 24/25J same as 20/21J, except with 4 top valves
Conn 26/27J same as 22/23J, except with 4 front valves
All of the above normally have large, short-throw valves with offset pistons.
I have personally seen or played all of the above, except the 23J and 27J. I own a 26J that I dearly love, except that it weighs a ton.
There are rare exceptions...and at one time, one could order both an upright and forward bell or an extra fourth valve keyed instead by the left hand, etc.
Best of luck!
