Prewar Buick Hubcap Identification

[TexRiv_63]

I have a number of Buick and other makes threaded hubcaps. Does anyone know a good source to identify the year and model different types were used?

I'll bet that if you post pictures here you'll find out exactly what you have...

OK here are the two I have now, the first is aluminum and the second is nickel plated brass.

 

My question about an ID source was more general. There are two very helpful websites that I use to identify radiator emblems but I have not found anything similar for threaded hubcaps.

There are others that have cars with those hub caps, but I would say early 20's.  For the most part block letters were used in the teens and script in the 20's

Don't know a website or other ID source's but the the one on top is installed on my 1928-51 and according to the "1928 Buick 120 & 128 Series Parts Book" available in 7 different colors (top of the cap, behind the BUICK letters) 

Mine have been re-chromed, thats why they are not colored

The aluminum one is a 1926 or 1927. The I.D. size will tell if it is for a Master or Standard. The block Letter example is 1923 and a few years earlier. Size will indicate 4 or 6 cylinder application.

Thanks. Can anyone expand on the size differences? The aluminum cap is 3 1/4" outside diameter, the brass one is 3 1/2".

Thanks. My aluminum cap is different from yours. Mine has a plain base with a simple stamping, yours has the fascinating "folded" stamping in the thread area resulting in double thickness metal behind the threads. Always wondered how they did that.

The 3-1/2" OD cap fits Master.  My Master alum cap measured around 3.55" and brass cap measured 3.51".

Standard cap for years 1926-28 is approx 3-3/8" OD and made from alum.  Mine has script lettering. 

Another cap in my collection is approx 3.3" OD, alum with block lettering  and does not fit a Standard hub. 

I have seen a collection of teens -twenties hubcaps identified by year yet cannot recall where.  Perhaps it was in a Bugle article ?

My 1917 D-45 Touring has the second ones, nickel plated brass with block lettering, painted black behind the lettering.
