Look at the Sterlings you are buying closely. See which parts are moving and which are not. Read the Certificate of deactivation. You will prefer older specs with moving parts. The new spec seems to miss many moving parts, and they are replacing the bolt with a solid steel piece. But get them if everything is ok, because with the new laws that keep coming I have a hunch we won't see Sterlings for too long anymore. Remember in US they cut them up badly, so in EU is much better even if new spec. But EU Sterlings cannot be sent to US, the US buyer might be in huge trouble with the law there, if having these deactivated differently than what is required in US.
You will need the following parts to make the E-11 conversion:
- T-tracks (preferably plastic like the screen used) - you can get Roy, Gino, Marv and a couple other versions; you need to bend them to fit in place
- M38/M40 Sherman tank scope or M19/M32 scope - you can get originals or resin/metal replicas on FISD, prices vary a lot
- scope rail made of steel or aluminum, you can get a separate bracket for the Hengstler counter or in one piece with the scope rail - again you can find them on FISD if not wanting to make them yourself
- Eagle Hengstler mechanical counter with metal sleeve (just Eagle logo or Eagle with text, your choice) - you can get less accurate counters with plastic sleeve for cheaper, or even cool replicas on FISD
- mag cylinders - the best, hands down, are from PWC on FISD, but he has taken a pause in making them, I think there are still a few other less accurate options out there on FISD or like etsy or Shapeways for example
Good luck
