@Ray - I do remember Ivor Mairants, and I bought a guitar a year ago from his old shop, now Mak’s Guitars.

@Fred - does it really matter? If your action needed lowering, and you used a new saddle, the (unadjusted) old one would be too tall, so pretty much useless. Saddles are pretty much regarded as consumables and are easily replaceable. I took the original saddle out of my D-18 and replaced it with a new, much better one from Bob Colosi about 12 years ago. The new one is still in the guitar, the original one is somewhere in my ‘stuff’ drawer, I haven’t seen it for years. If there’s ever a need to replace the ‘new’ saddle, I’ll just get another ‘new’ one.

But I don’t get emotional about guitars, and I don’t worry about keeping things ‘original’, it needs to do what I want it to do, and if I want to change something, I just do it - so my D-18 has Waverly Tuners which replaced the Gotohs it came with, and which I gave away, the bridge-pin holes are reamed and slotted, and the plastic slotted pins replaced with solid (unslotted) ebony pins, I put a strap-button in the neck-heel, and installed a K&K pickup.

But that’s just me, and I realise my way isn’t everyone else’s way - to each their own, just as it should be.
