It's quite possibly one of those that were originally fitted to the modified PPCo rings (?? Bartle ?? mounts). A nice piece, but very expensive. I recently picked up a clean example of an Aldis for 800 GBP, which was not a steal, but was reasonable. I would have thought a mountless but clean scope is probably worth somewhere in between what I paid & what matey-peeps is asking for his..................

I suppose it all comes down to how badly you want one.
