Hi Edwards, and welcome to the forum :)
usually, if it's worn bearings internally in the g/box it would be noisy in all gears, and if it's a worn clutch release bearing it is noisy/rumbly [when parked up, stationary, in neutral with engine idling] with the clutch pedal pressed down, but not when it's up, [if noisy when clutch is up in neutral, most probably worn internal bearings]
suppose it could be worn roller bearings on some, but not all gears, not an expert by any means, but have rebuilt my 5speed which had totally knckrd a roller bearing but only rumbled in 3rd!
you could do with a second opinion from a knowledgable T25'er really, someone on the forum called Aidan [beaker] is well clued up on gearboxes, he would be the one to speak to , hope this helps,
cheers. :)

Mine used to do similar and it was caused by incorrect adjustment of the long gear shift rod.

It was not allowing the gear lever to have any free play towards the front ( tho on mine it was in 2nd and 4th )

Cured by undoing the clamp bolt near where the rod connects to the actual gear selector thing on the gearbox and trialling a few guestimated settings, till I found a position that allowed the usual bit of movement in all planes of the gear lever in each gear. It took a few trial attempts but I got it so it is now just fine.

you can end up getting unexpected gears where they shouldnt be when you start playing with the link rod adjustment, as you've found!
worth trying to very carefully set it up exactly how the haynes manual tells you with a spacer, this is a bit infuriating and fiddly and ideally, you need a second person, but prob worth trying just to rule out the linkage set-up as the problem.
