Jaybird:
I have a 504-A (nice wood case), with a tube update printout of about 5 pages - I can email the .jpgs of scans of each page (about 250KB each) if you like - don't think the tubes listed will go into the 50's and 60's, but it's more than what is on the roller.

Just sent them in three separate emails - let me know that you got them OK.
