This antique printing block (along with others we currently have listed on eBay) comes to you estate-fresh from an old Brooklyn, New York brownstone that we recently liquidated.  Found packed away in the old basement workshop they most likely haven't been touched in several decades if not more.

I'm not sure what the gadget depicted here is.  Perhaps part of a larger machine (like a newspaper printing press - perhaps to distribute ink?).  No notations present but many of the other blocks we're offering are related to/stamped "R. Hoe & Co." so this might well be from them.
Metal on wood construction.  Measures 3-7/8" by 2-1/8" by 7/8".
Overall nice antique condition w/ a century's worth of general wear.

Check out the other blocks we've got listed.  Buy several and save on combined shipping.

Cheers!
