Map Table PIU 700x700mm Restoration–The Planning
The planning of restoration took around two to three weeks.
The only source was to collected all pics on the forums, enlarged the parts and made my own drawings by the old holes and marks on the wood.
From these drawings built some plastic models for test, have no 3D printer all are hand cut by modelling PE sheets.

F. D Ring with mount x2
Brass:
Brass angle 3 x 20 x 18mm –L91mm x 2
Matching brass angles and brass screws, later learned that the new brass screws are anti aging (always in shining gold color), which is not match the vantage brass looks, reordered old new stock vintage brass screws but only has 48pcs, lucky to match with the 12 good screws to completed all 60 pcs for four brass angles.
Later found the imperial old screws are a bit larger than the original metric screws, and the shining screws can be aged by Gun Blue. What a waste of time and money!
