Can read the tag that says drain and renew oil every 500 miles. The tag in the second to last photo is on the engine oil pre heat / separation filter unit. It uses engine coolant to heat the oil on warm up. With the oils of that time they had a tendency to coke up and cause a feed drop hence the 500 mile change intervals. That was run until the early 30's. That is an early engine with the primer cups on the heads.
