Masting on British 1st rates 1800

[dafi]

Some questions about the masts of British first rates about 1800.

 

- Usually the heel of the topmasts is shown squared, the heeling on the Vic in P. is octagonal, as it is shown in Lee, who states that  "Octagonal heeling only on 1St rate ships and by 1773 on all rates"

Are there any contemporary sources confirming that?

 

 

And another question arose: The cleat for the jeer block lashing are shown in Portsmouth as a clamp, but most of the literature shows a shoulder piece. What is the correct setup? Was the cleat an earlier or later version?

Here both of them together for comparison ...

... and here the shoulder its the right place.
