B F Sturtevant fan coil capacity?

Can anyone help? My customer has a very old system and part has been removed. He is replacing a steam boiler and is figuring the capacity. The coils are much like fin tube, have duct off the back, can't tell you if their is a blower or just outside air. There two 12"dx27wx34"h. Model 331616 10-design 175-size. They are no longer in business. Anyone out there have any ideas?

    If all else fails

    use the capacity of the runout pipe to the coil. It might have been oversized but probably not by much.
