there are 2 in the hull of "Polish S3" at Hoo on the Medway at our end of the world ; looks as though i'll have to try and dig them out. - cos HSL 102 is in need of one as well!! - peterh
BUT they are NOT licence built Merlins - those are GENUINE Packard "through and through" - still V-12's but producing a lot more Horsepower than the Merlin's - peterh
yes - there was one listed on here - in a scrapyard - but in Malta!!
and yes you can run them - just have to a) tie them down b) ensure that you have a good "raw-water" supply going in the right "hole"
