Rather than taking over other threads (Lions in the Sahara a few months back) I thought it best to start a dedicated thread on surviving Napier Lions. It can start off picking up on the UK list and perhaps, if there’s enough interest, go ‘global’
Will post an updated list tomorrow but in the meantime I have started a complimentary/cross reference list of known Lion serial numbers.
Question – where abouts on the Lion is the serial number?

Hi all aero engine enthusiast’s,
I have made further progress with the Lion rebuild, the arrival of the piston’s was a major step forward, all the major assembly’s went together without too much drama.





I am alway’s looking for any Lion part’s, if you know of anything please get in touch.

This is the one in the Malta museum last week,,,

I’ll try and find out when I go back in a couple of months.Its a really good little museum, what they have done with the Spit and Hurricane is quite amazing.

Thanks again John, it is great that you can see the screw-in valve seats that hold the cylinders to the heads and the valve decompressor rods.
Has the aircraft that had this engine fitted been identified yet ?

Here’s another then….

Hi PanzerJohn,
Thanks for the best shot of the Malta Lion engine I have seen, it really shows the workings of the engine well.

What achievement are the Portuguese so proud of (with a Napier Lion engine)?
from Wikipedia
A single example of the Fairey III is preserved in Portugal’s Museu de Marinha (Naval Museum). This is the airplane that finished the first aerial crossing of the South Atlantic.

Portugese Air Museum
I dont know if the replica has an engine or if the original has. The outside stone one certainly does not!
Note that although there are 2 photos of a “real” Fairey 111D the first is a replica at Alverca and the last is the original at the Naval Museum

Engines Galore!
I stumbled across a website with some rather nice photographs of the Napier Lion preserved in Portugal (it confused me somewhat as it is a site from the Czech Republic).

Some other gems in the engine collection there too!

Looks good Andy. Should improve the draught!

Hi all,
I have just collected a 4 blade test club for the Lion engine, I am really looking forward to it’s first running.

Hi all,
After the ‘egg-on-face’ of not realising which Lions had the central bank inlet and exhaust reversed I had a good look at the various marks and can’t see any reason why it is just the VIIA and B that were built that way. Its not related to having the carbs. moved to the rear nor to any specific requirement in the two aircraft for which it was designed (Supermarine S5 and Gloster IV). Neither is it to do with the Schneider contest course layout in 1927, that was flown anti-clockwise the same as all the others. Frankly I’m bamboozled, anyone got any bright ideas?
Cheers

Hi Andy,
Right, so then the question is why they would have swopped the VIIA and B to the other side? I don’t have an answer to that.

Evenin Schneiderman,
The IIB, VA and XIA’s are the same exhuast/inlet set up for the middle bank as the VIID,

The VIIA and B are the opposite,
