How can I tell if struts were replaced.
I have a '88 N/A 944. Is there a way to tell if the struts have ever been replaced. The markings on the sticker are:
Sachs Super Touring.
Do not open-gas pressure.
100 723
11 1500 100 723
These are on the strut assembly itself, not the shock part. If this is the original assembly how can I tell if the cartridge has been replaced. The boot is shot and there is an orange foam looking bushing at the top of the shock. It's crumbles if touched. Cartridge is black and isn't badly corroded. No markings on it.

11 1500 100 723

My N/A is 99% bone stock... I liek it that way, gives me contrast to the fully modded 951...
Late N/A Boge/Sachs struts are not catridge type.. they are crimped at the top... early style struts are screw top rebuildable with replacement cartidges...

Most likely after market. I just checked some after market shocks I have lying around supposed to be for 1988 N/A and they are Sachs Super (not touring) The part number is:
100 666
11 1500 100 666
and
100 665
11 1500 100 665
The part number seems to be similar to yours and is not a Porsche code. I would expect the original porsche struts to have the porsche code written on them.

11 1500 100 666

As many on here could relate, the "hacksaw" modification on the strut housing itself allows compatible inserts to be replaced in the future, since the insert is held by a bolt from the bottom of the strut housing. You can modify/hacksaw the existing struts on your car, and for example install a Koni insert kit.
Paragon and Pelican sell the kits for the insert/hacksaw project. Paragon even will do the strut modification and insert install for you if you send in your struts. In addition, Paragon has an adjustable ride height kit that can be installed at the same time if you also want to change (probably increase) the front spring ratings.
I did this exact project last year, and am happy with it. Since mine is a track/street driver, I only went with 250# springs. If I did it over I might have gone a bit higher, but too high exaggerates understeer, etc. Like I said, you can find a lot of stuff on this topic.

After some research I see that the INSERT has to have the bottom bolt provision for the hacksaw job and not all inserts have that. Besides Koni what are some others that do?

I was transfixed on Koni's from the start, so did not learn about other insert options out there. But having done the rebuild, I can't see how any kind of shock insert would be held in the strut housing with something other than "fasteners" of some design. One idea: I could imagine a collar with set screws of some kind holding the insert at the top of the housing, but nothing welded or irreversible.
It would be interesting to hear what attachment methods other retrofit shock inserts use if not the Koni "bottom bolt" method. That seemed to me to be an elegant solution.
