Solid rudder ruddertwins

[smokeonthewater]

So what is the deal with solid rudder rudder twins…… Were the earliest motors just built that way?
I’m confused because I recently came across an early serial numbered model "a" and it has the hollow rudder with propello-pump. And a square gas tank
So, Which motors would have the solid rudders, and are they all that rare?

what I thought ;
only numbers on the ID plate ( f.e 2121 )
ID plate has black color ( not blue )

In most cases the solid rudder was standard on R/T ‘s 1921-23.
The "T Bar" on the solid rudder measures approx 3"
I have an early R/T (1922) with a hollow rudder as well.
My understanding is that hollow rudders were offered as an
upgrade for the earlier R/T motors in later production years.
You may find the conversion steering " T Bar " to be approx 5"
In length to where it meets the rudder on the early square tank motor.
In 1924, what I believe to be the start of the hollow rudder motors,
the model C steering " T Bar " measures approx 7".
The model D ( long shaft R/T ) measures approx 10"
In my opinion the 5" T Bar is unique to the conversion kits offered for the early
R/T ‘ s.
Opinions may vary.

All measurements were taken from motors in my collection
