You did well. I paid a little more for 67SS-A off ebay.

Thanks guys... it’s headed to a good home now.

that could be incidental. I've had two LM45 reels with two different spindle diameters. I kept the one that matched my Browning MZ34, kept two matching spare spools, and sold the LM45 and spool with odd spindle size

yes, and I had two LM45 plus one Strada MZ34, with 3 spare spools - all purchased separately and new boxed - the Strada matched one of the LM45, along with two spare spools, but one LM45 and matching spare spool had different diameters from the other four.
If Martin decided to change spindle size, it wasn't because of model, but because of production stock.
I'm sure Steve and anyone else with a large number of Martins can come up with similar examples.

Even Hardy did this to us on Lightweight series reels.
The worst for random dimension changes are the Olympic/Seiko Hardy clones.
I had a Heddon that fit a Berkley spare spool, where the Berkley reel wouldn't, and an Eagle Claw that didn't fit the spool it came with.

The Martin SS reels are very sensitive to spindle alignment.
Reels that have been dropped inevitably rub the rim on the faceplate ring.
Took me awhile to adjust out the rub on an LL Bean model.

had an Angler 1 and Angler 2, but never compared spindles.
I remain not a huge fan of the SS reels - sort of seem like an afterthought - but love the clean-sheet-of-paper LM/MZ poor-man's CFO.

Very ambitious to keep check all those fits. Keeping them straight, even more ambitious. Don't know if I could do it even with a dozen of mine placed out in a row. I have bunches of extra spools but am not much of a spare spool swapper, preferring to carry spare reels. They don't all interchange, that's for sure.

For repairs or replacements to make better use of prefered spare spools on a prefered frame/reel body, the spindle is relatively easy to change, so one of a different size, (let's say, from a junked out parts reel) could be installed. Let's see. Use a good-fitting gunsmithing screwdriver. Apply penetrant and let it work for a good little while. I think the spindle screw is reverse threaded. Don't force in trying to loosen or it may shear. More penetrant and just the comfortable effort that the tool enables.

that issue is drag v. click-pawl. Martins are poor-man's Hardys.

The drag reel spool has a clutch plate where the click-pawl reel spool has a drag gear.
The Bean DS reel may be a proprietary assembly, with no equivalent Martin model.
Not sure how this discussion ended up on four different threads.
