Hi Jeff
The 610B tombstone uses a 5 inch (not 5-1/2") P-27 speaker with 1146 ohm field coil.
The 610T "Bullet" uses an 8 inch S-14 speaker with 1140 ohm field coil.
The 38-624T uses an 8 inch KR-17 (permanent magnet) speaker. I don't have info for the 38-624 console but the 1937 version (37-624J) uses a 10-1/2 inch HR-12 (PM) speaker.
A 38-624 chassis will fit any 37-610, 37-611, 37-620, 37-623, 37-624, 37-630, 37-640, 37-641, 38-620, 38-623, 38-624 and/or 38-630 cabinet.
If you are limiting yourself to "Bullet" cabinets: 37-610T, 37-611T, 38-620T, 38-623T, 38-624T.
The 6 volt battery for the 38-624 would have been outside the cabinet.
I'll let someone else answer the amp-hours question. You will need to determine the current draw of the filaments and the B+ if the service info does not give this info (and it should).
