Look Closely At Materials.
Antique Telescopes Generally Have Tubes Made From Brass, Pasteboard Or Wood.
Those Used By Sailors Tend To Be Bound With Plaited Rope Or Mahogany, While Military Pieces Are Finished Off.
If The Brass Is Not Too Badly Marked Then A Light Polish With Brasso Or Solvol Autosol Or Any Other Mild Polish Should Suffice.
Then Thoroughly Clean And Dry The Tube.
Always Handle The Polished Unlacquered Brass With Gloved Hands As Your Finger Prints Will Tarnish Eventually And Show Up.

Galileo Galilei (1564-1642) Was Part Of A Small Group Of Astronomers Who Turned Telescopes Towards The Heavens.
