Leitz Wetzlar Drawing Tube Attachment Part
Not complete - see photos for more details.
Requires white threaded intermediate tube which is block-shaped as seen in searches on google under Leitz drawing attachment
Each extension/segment moves freely and smoothly. The one throat lens has a minor scuff on it but otherwise the optics and mirror are clean and clear, ready for use in a rebuilt drawing attachment system.
As is, for parts - 100% guarantee.
