   I would tend to think more the 250s - the 450 envelope is 12-1/4" from 
pins to plate cap, and 5-1/8" max diameter.  From the pics - it doesn't 
seem that there'd be that much side clearance in the final compartment - 
dunno - hard to tell exactly, although including the ruler was quite 
helpful!

   Cheers
