Description:
This is a series of 5 empty glass tubes that were used to build vacuum tube arrangements. Each has a small round sticker with numbers 034 to 038.
034 is an organically-shaped, clear glass tube with extremely slender, tapered ends and a larger central component.
035 has a recessed center with a closed, curving end and a pointed tip. There is a protruding form near the center with a hole in it.
036 has a long, clear, cylindrical shaft that is somewhat soiled and cloudy and marked with a Pyrex seal near the open end. The other closed end has a narrower, bulbous tip.
037 is a cylindrical at the top with a stick-like component with a square end that seems to have been broken diagonally.
038 has a brass cap on one side, a metal component inside, and a small handle in the middle. The rest of this tube is cylindrical at the top with a slightly-pinched center and a stick-like component with a square end.
