Its usually the third gear synchro that causes trouble not second.
The cause is repeated rushed downchanges. Basically a synchro hub is a a device that synchronises the speed (hence the term synchro hub) of two gear wheels that are rotating at different speeds so they will engage without graunching, the faster you try and change gear the harder the syncrho hub has to work, and they do wear out !!
You MAY find that if you slow your gearchanging down CONSIDERABLY ( try SLOWLY counting, "one thousand" as you come OUT of third gear, pause for "two thousand" with the box in neutral and THEN say "three thousand" as you select second gear) the problem may ease, also try not to let the engine revs drop off as you change down, in fact they actually need to INCREASE slightly, (try not lifting your right foot when changing down, or just lift it SLIGHTLY) it all helps to keep the gear whels rotating at similar speeds which means the synchro hub doesnt have to work too hard. each gearchange SHOULD take you in the region of two to three seonds to complete smoothly. You should aim not to feel any gearchange up or down. It can be done trust me, in fact if you get the engine revs matched correctly to your road speed you can change up and down WITHOUT using the clutch at all. (except for pulling away from rest)
Any repair is going to be expensive because of the labour time involved. It will be cheaper to have yours repaired than fit a new (or recon) one !!
I have a 3 Litre with 29K on the clock and the gearbox is like silk up and down. I would suspect that the previous owner had no finesse at all when changing gear.
If you can find someone to teach you how to double declutch that will alleviate the problem greatly (an old time truck driver will certainly know how to do it!!)
Its not the destination that matters.
It's who you share the journey with (even if like me, itís in a caravan!)
I am very fortunate to have Mrs Plodd to share mine with
