Ok....  I am learning as I go along here...  
 
Here is another  box presented to me by the TBC gods this week also in  a 
1u  form factor....  little more bandwidth but dunno if it is going  to work 
better for the black and white......
 
i was also gifted some black burst gens also...

Prime  Image  
The Prime Image Model 50II is a high-quality, multi-featured TBC /  
synchronizer ideally suited to a wide variety of video production applications.  In 
addition to offering full transcoding of composite and component signals in 
 and out, the Model 50II provides full proc amp controls and many extra 
features  usually found in units costing considerably more. For example the 
Model 50II  offers automatic gain control (AGC on/off) horizontal position, 
vertical color  advance (1,2 or 3 lines), horizontal chroma-to-luma 
adjustments, three levels of  detail enhancement, variable rate strobe, and 
ultra-stable freeze (frame or  field). Options available for 3-way adaptive comb 
filtering, hot switch, and DC  power.Control Options:R1 Remote Control - RS232 
handheld remote control for all  Prime Image products with an RS232 port.R2 
Remote Control - RS232 rack mountable  remote control for all Prime Image 
products with an RS232 port.      
Standard Features:
 
    *   Composite Y/C in and out  
    *   Transcodes Composite and Component inputs to all outputs  
    *   Inputs may be synchronous or non-synchronous  
    *   Works with all VCRS  
    *   AGC on/off  
    *   Vertical color advance – 1, 2 or 3 lines  
    *   Horizontal Chroma-to Luma adjust  
    *   Detail enhancement – 3 levels  
    *   Ultra-stable freeze (frame or field)  
    *   Variable rate strobe

I agree completely with Chris's  comments.   If you have off-air recordings 
of broadcast  video, then as long as the TBC will deal with the lack of 
burst,  you may be OK.  The problem comes with tapes made from B&W  
non-broadcast cameras.   It was VERY common in the days of  B&W EIAJ recordings to have 
cameras that did NOT produce RS-170  sync.  At the worst, many were random 
interlace.  The next step up  was fixed interlace, but often without 
equalizing pulses and with  non-conforming widths for sync and blanking.   
 
In modern-day equipment, just about everything that uses a  composite video 
input expects to see burst present.  In doing quad  transfers, there can be 
problems with B&W quad tapes due to the lack of  burst, necessitating the 
addition of burst before the signal is  usable.

This brings up some more cans of worms.
 
Is the sync on the tape NTSC EIA sync?  If not, the TBC may not  recognize 
the Vertical interval and memory addressing will be an  issue.  Plus if not 
interlaced, I have no idea what will  happen.  This is experimental 
territory for me.
 
Next, you have to make sure that the TBC will process Black and White  
signals.  A multiple of 3.58 is used in all TBC's to generate a write  clock.  
Usually 4X but also 3X.  If there is not a color burst,  then the TBC has to 
generate a write clock.  Many times this is done  with an oscillator that is 
referenced to the H sync frequency.  Make  sure that the TBC can do this.
 
Wish you luck with this one.
