Marine Radio Regulations early 1900s

I require information about marine radio regulations that prevailed in Europe in the early 20th century. Can a person well conversant with the history of marine radio communication provide me with an e-mail address, for me to shoot across about ten questions?
Many thanks.

Why do you want the email address. Suspicious. Ask your questions here in open forum.
Members do not give your email address.

Mea culpa.
I did not think all readers would be interested in my questions.
To clear all suspicions, I am researching a 140 GRT schooner lost in 1933 with all hands and no trace. She did not carry wireless of any kind.
I may write a book about this event.
A sample of my work is at :
https://www.amazon.com/Plotting-Glob.../dp/0275988953
More questions were asked at the Ship Rsearch forum.
Here are the questions. More may follow.

When were Passenger ships first equipped with W/T radios?

When were cargo ships first equipped with W/T radios?

When was 500 KHz established as the distress/calling frequency for marine W/T?

When was it first internationally regulated that ships should carry radios?

When was R/T first used aboard merchant ships?

When was 2182 KHz established as the distress/calling frequency for R/T?

In 1933, merchant vessels of what size (GRT?) were exempted from carrying radios?

What could have been the price of a basic marine R/T Transciever in 1933?

When were call signs first allocated to merchant ships?

Thanks & 73
