MJF, hello mate and welcome to the forum and M3W ownership.
As you have quite an early model, you should have all the upgrades but best to check.
Presumably you bought this from a dealer?
If you have an up to date service manual, it should all be logged.
What mileage do you have? This would be a good indicator as to whether it has been changed or not.
Early BBs were bolted directly to the chassis. Later ones had an isolation mod. This really does not make a lot of difference to the noise level. It just adds weight.
If you have a noisy Bevel Box it will very likely remain noisy.
However, different oils seam to have varying results regards noise. Miller oils EP 140 has a high recommendation. Scheduled oils changes help as well.
There is quite a lot of chatter here about it.
There is also a thread about sound insulation. This helps quite a lot to.
Have a look at Morgan customs.net. Emil has made several mods for the 3 wheeler.
Phil Bleazy has made his own BB kit with very good results.
These are available at a very competitive price.
Should you need one, and you are average with car repairs you could fit it yourself.
Best of luck.
John.
