There are actually 4 different horns made by Delco Remy for the 125/165. The 47 and 47 A are both 2 leaf horns. The 47B is a 4 leaf horn, the -62, which is a model S if memory serves me right, I have one out in the parts room) is also a 4 leaf horn (this horn was a replacement horn for all earlier generator 125/165 models,but was used on the 62-63 Servicar and the 62-64 Sportster XLCH models).

I have seen atleast one completely unmolested 4 segment horn that has the model 16 washer. My guess would be it was super early production, like near the end of 1955, when the 4 segment horn came into use. Also, all 3 Delco Remy production horns for the lightweights have a number, stamp-painted on back side, on flange right at the edge. The 2 leaf number is stamped at 3 o'clock when looking at the back of the horn with the brackets at 12 o'clock. The 4 leaf has the number at 7 o'clock, ditto.

A few weeks ago Dave posted a question about the difference between the horns used on the lightweights over the years. I discovered today that the only difference between the early 2-leaf and the later 4-leaf is that Delco-Remy quit using the "16" designation and marked them as "Type M", there appears to be no other difference, internally both types are identical, externally the only difference is the 2 extra leaf tabs for the mounting bracket. Dave, I have a bunch more pictures I could you if you want to add a horn chapter to the how to restore section. check the response to your original question, I posted a pic of a 2-leaf DELCO-REMY-16
