“VALOR” OIL CABINETS.

Price trom 39 - to 120/-

You will obtain, by using the “ VALOR ” Oil Storage
Cabinet, the most economical, cleanly, and the only perfect
system of storing ALL KINDS of oil for daily use.

The quantity of oil lost in leakage from barrels on tap
is considerable, and greatly increases the risk of fire. The
saving of this leakage will pay for the Cabinet in a short
time and also obviate any danger.

Taps in barrels or tanks are often left running, and
measures overflow—any overflow runs back into the well
of the Cabinet.

Capacity 50 30 20	12	6	gallons.

Price	491- 431- 40- 331- 281- each.

THE MONEY YOU WASTE every
week through not filtering your dirty
oil would soon pay for the “Valor”
Patent Oil Filter —AND LEAVE A
HANDSOME PROFIT BESIDES.
