Found this thread describing MX347:
Sounds like it was a very hard-hitting mix with fast effects.
Did MX347 evolve into the A314 spray versions and if not, is there any chance of it making a re-appearance?
It sounds like a very interesting mix!

Yes, it was the prototype for A314 spray and yes, it was excellent although it did tend to be a bit heavy going compared to even the A314 oil of the time.
With the right woman - i.e. tuned into very mature status, it could be superb and very fast indeed. Although fallout did still take some time to develop fully.
I’d certainly welcome its return. 
There are a few missing-in-action MXs that seemed really good. It’s sad so many of them disappeared without a trace.
The ones I miss most are MX301 and the aforementioned MX347. 301 in particular was eminently steerable/adaptable with a range of products/putatives and I notice the recipe released after its demise also seems to have been removed.
Quite a few others were released though, so you can have a go at recreating them yourself.
Thanks Mobo, it’s good to have my suspicion confirmed 
Was MX301 a social, a status or a sexual type of mix?
Cheers, SH
Definitely a sexual but with excellent connection/attraction properties as well. IIRC it was P93 and None-based.
