Fore-Topgallant/Royal Mast
The combined topgallant and royal (TGR) mast was the uppermost spar in the foremast. According to various sources, in the latter days of merchant sail, it was customary to combine two or more of the upper masts into a single spar, eliminating the mast doublings common in earlier eras. I am not familiar with the reasoning behind this evolution, other than it simplified the construction and rig somewhat. In the case of Galilee, this upper mast carried the the topgallant and royal sails, and included a bare top pole.

From a distance, the TGR mast appears to be basically a long tapered pole. However, when examined in perspective, the construction is more complicated:

Ignoring the mast base for the present, the mast has three distinct steps. The lower and middle steps provide stops (or hounds) where the topgallant and royal backstays attach to the mast. The uppermost step is simply the point where the metal truck is attached.
This view shows the typical design of a TGR mast heel. Note the offset, which provides room for the ratlines and stays. (Blender)
As with the topmast, the heel is provided with a slot to accommodate the heel fid to support the mast on the trestletrees. There is also the slot for the top rope sheave. Also, as with the topmast, the upper point of mechanical support for the TGR mast is the topmast's cap ring. Again, I probably should have modeled the ring with some space to allow for a sliding fit!
As will be seen in future posts, all the spars on this mast have sliding yokes. So the TGR mast has tye sheaves to hoist and lower these spars into position.

The "funnels" were employed to mutually protect the mast and stays from wear. (Blender)
The final, physically-attached metal part on the TGR mast was the mast truck fitting. There is no good image of this part, so I mimicked a design provided in my references. Some indicate there were actual sheaves incorporated into the truck while others show they were simply U-shaped channels cast into the fitting. I have no clear photos showing the employment of the foremast truck and the mainmast's truck is completely different.
