Antique W. M. WELCH SCIENTIFIC CO Resistance Wood Spools Circa Early 1900's
The wood on the spools is in very good condition and one display appears to be complete, base measures 8" x 4" x 3/4".  This listing is for all shown in pictures.  Not all labels are secure, a couple may be loose.
I literally found these in a wood cabinet that was in a crawl space at a school that had been built in 1912.  I am happy to combine shipping ~ please see my store and other listings!
I DON'T KNOW MUCH ABOUT THESE ITEMS, BUT PLEASE SEE ALL PICTURES.  I'VE TAKEN AS MANY AS ALLOWED!
