I've been working on the fairwater on mine cutting it down and started on the PE sheers, made a mistake on those and had to take them apart which is just as well since I need to modify them a bit to be correct for my boat.
I also removed most of the storage canisters and filled in the mount points for the propeller guards since my boat didn't have them.
My hull didn't have any warping, so I'm fortunate there.
Keep in mind that the model depicts a post war boat so the marker buoys are the wrong shape and wrong position.
Don't bother with the ISB markers they are wrong, the details are soft, incorrect an the railing on the edge should be done in PE.
I actually did a test in sheet brass that seemed to work but I bent it to much and broke it.
The Edward PE deck set has the same problem with the post war buoy covers.
If your doing an all wood deck than fixing it won't be a problem.
The model is also missing the exhaust openings and flood openings on the bottom.
Those will vary depending on yard and series in the production.
limber holes on the sides will differ depending on the yard, production series and mods made during refits, fairwater and deck details will vary as well.
No 2 subs where alike.
You might want to have a look in the Fleetboat Dock section on the SubCommittee forum and also the AMP forum for info on the boats.
On a side note, for those intrested I have some Sonar Heads for sale, Solid Brass.
