[Brass lamp lenes??]

Go on eBay and look for convex clock lenses. Available in many sizes

As J&J mentioned - Paper Pulleys - this is a rare case of being able to buy new brass era parts from the original manufacturer.

There's no number - you use Facebook messenger to contact the seller in most FB ads. You'll need to make yourself an account - that doesn't mean you have to use it for other stuff!

[Brush Information Needed]

Compression ratio and operating speed for early engines are rarely mentioned - but both are quite low, due to the metallurgy and designs. Car engines are (usually) a step up from hit & miss engines - which can run slower than 1 rotation per second (60 RPM). I've heard a single cylinder Olds running perhaps as slow as about 100-200 RPM anyhow - with a later style carb. (which has better adjust-ability) The brush could be similar. I expect the C/R might be around 4:1 - maybe even less, probably not much more. I've thought more than once about digging up a tachometer that can measure these cars - remember, they may be running on a buzz box or magneto ignition, so an external voltage source for an electrical tach is needed, or a mechanical / optical tach. 

 

I searched through my 1918 Dykes Automotive Encyclopedia, and did not find good listings for either. Did find a reference about SAE horsepower ratings - such as a car listed as a 25 / 30 HP car - the 25 would be at 1000 RPM, and the 30 would be as tested on a dynomometer (no RPM listed)

 

I've seen the 1908 Ford model T listed as 4.5:1, and engine speed of at least 1600 RPM.

[Reo 1905-08 two sill plates wanted]

Max -

Did you ever find any plates? I'm looking for one plate for a 1909 touring (yours looks shorter and curved - a runabout?). A weathered  one would be great, and match what's on my car.

[1926 REO t6]

How are you going to measure anything with only one meter lead connected? Connect one side to a good ground, then you can start to measure the voltage.

Nice photo Frank -

 

It's known for knocking Barney Oldfield upside down in 1905. There's a few references on firstsuperspeedway  - be sure to follow the links to pdf's and articles.  Referenced as "32 hp" - and the stock REO 2 cylinder was 20 HP.

Referred to as the REO Red Bird in this article - http://airportjournals.com/barney-oldfield-master-driver-of-the-world/?fbclid=IwAR05ysG6VGoqR2_gMZPtPOR71zO_51IgKV3JU0lwZgXpMsL-TeRemD7fu3U

 

Another photo and some good clippings here on The Old Motor, in 1906
