Identify this ASI ?

I thought i found out what it was from because there is a picture on thunder and lightnings page of a gnat F1 cockpit and the ASI looks identical, but then i was told that the Gnat didnt fly until 1955 and my ASI is from 1951, so it cant possibly be from a Gnat,

I may have been manufactured in 1951, but it’s entirely possible that instruments such as these sat on shelves in store for several years before installation in an aeroplane.

I am taking it to the Solent sky museum to see if anyone there might have a idea what it is from.
Are there any books with aircraft codes in that i could look at to see if i can find any of the codes on the label on my ASI?, I did find a list here with some aircraft codes and manufactors codes, and i found 2 codes that i have on my ASI which were AS/PC according to the list i found AS is the airspeed manufactors stamp (although that coudl also refer to it being an air speed indicator) and PC is the aircraft code for a Battle (Fairey Battle I’m asuming as that is the only aircraft i can find called a battle) but this ASI cannot come from one of those as im sure the battle was not capable of the speeds on the ASI.
My quest continues!

Hi guys,

while we are talking aircraft parts can someone please tell me about the range of control colum grips used in early Harriers (up to GR.3/T.4).

I know what a GR.3 grip looks like and would prefer that type, but I have seen another type of earlier grip described as ‘Harrier’ (Corke Aero had one years ago).

Is there a differance between Gr.3 and T.4 grips?

cheers,

-John

Just a quick note……..
I have found out that Harrier GR.3 & T.4 aircraft used the same grip. (The one with the lump top/right side with the spring down trigger in it).

thanks

Thanks for helping me, i have since managed to rejoin as i contact the admin and found out the reason i was unable to login, because some of the old accounts had to be deleted because spammers were using them, or something like that, so i am glad to be back!
there are some codes on the ASI which are, CODE 147AS/PC, MOD 01, SER NO 171/51, BRIT PATS 543257 it also has a military broad arrow.
On the front it says 50-600 underneath the word KNOTS and it also has a number, which is probaly the most important number to find out what plane it was fitted to, but i cant read it as its partialy obscured by one of the pointers, all i can make out is TYPE 1-1.
It was made by Smiths, hopefully this additional info will make it a bit easier to find out what aircraft it would have been fitted to, i have searched lots of cockpit photos and cannot find my ASI in any of them. i have seen similar ones but none that are identical.

Nah, s’not mine – posting this for someone without access.

My “clearout” will be chucking stuff in boxes and then loading them into your boot 😉

Can anyone possibly identify this ASI ? No markings, wonder what aircraft it might have come from.

Thanks.

Having a clear out are we?! 😉
