334-06 Gearbox identification

[Geoff in the Gully]

Hi Guys,
I'm cleaning up (mild restoration) a 4-speed 334 gearbox to replace the 3-speed on in my '64 1123.
The identification tag on the box says it's a 334-06.

I haven't had any success in finding out which vehicle model this box came from, and what might be different about it compared to others.
Might be an issue when getting parts.

I got the box from a deceased estate so I can't query the source as to it's origin.

Does anybody know what it might have come from?
OR any documentation referencing the 06 variant?

Thanks, Geoff

Hi Geoff, are you sure it's a 334 box or if it states 334-05 on the tag?

There should be only 328 box with -06 marking.

I shared your scepticism; I checked the tag several times thinking I had misread it.

But no, it is very clear - see image

The gearbox itself is absolutely a 4-speed 334.

Could it be an R6 box? Apparently, this box had a 'lowered gear lever' design. The MR145 should tell you (sorry, I don't have a copy):

Pardon our interruption...

Indeed from a Renault R6 R1180 as @Andy McGhee wrote.
