I picked up a lot of Manuals the other day and found a gold-mine
of older tube scope manuals. They range from the 502 to the 661.
Also some of the 5000 series scopes (50XX, 51XX, 54XX, etc),
and most all in-between. Let me know if you want to see the list.
They can be sent USPS Priority Mail, and are priced at $15 each,
if they fit in the Flat Rate Envelope else it's $5 extra for the heavy
ones.
Shipped CONUS only.
No Manual Merchants need apply.
