Ethyl made anti knock compounds for most, if not all, cars. This is the data to match up the vehicle with the compound in 1947. It measures 7 1/4 x 4 1/4. The pages are not numbered. It is in nice condition and had holes to enable it to be inserted in a loose leaf binder. The staples are tight but show a little rust. We must collect 6% Pennsylvania Sales and Use Tax at checkout.
