Hi Gary,
the one on mine are defo makeshift ones, based on the design of the one on the top, but definitely too rough to be pukka.
I am going to get it probably next weekend, I will then inspect it properly and we'll see. Did you get my last PM? I managed to take some accurate measures of the wartime fins at Hendon.
Also, do you have any idea whether the AP head was screwed in place? I'd like to try and remove mine to do some restoration work to it.
Cheers

Hi A,
Yes, the AP head was screwed into place. Assuming the head has rusted in place it will probably need a good soak in diesel to help free it off. However you decide to secure the motor whilst undoing the head, do not grip it around the top of the motor where you will see a set of slightly proud pins. These pins secure a threaded collar to the rocket motor body and if nipped in a vice will press against the threaded boss of the head. Do not be surprised if you cannot get the head off ! it has probably been sat in seawater for a couple of years. How did the fins at Hendon measure up? I assume they are original? Cheers Gary

great, I figured it'd be something like that 
Re. the fins, they're defo pukka, they have a tiny detail I had never noticed: each face of the rocket fin is numbered! If you send me your email I'll send you all the details. I brought a calliper to get accurate measures, and the staff there was very helpful! You don't happen to have a spare AP head or know someone who might have one?
