Tijmen,
There is no reason to replace those cylinders.
There are places that will remove the old chrome finish and re-plate a new chrome layer back on. I believe Lister called their process "cracked chrome" and all they did was chrome the liners and reverse the polarity at the end to "crack" the surface. The chrome plating guys know about this process. Cost here in the US is about the same as the liners from India.
I have two cylinders that are similar to yours. I am planning on having mine re-chromed because I know the quality will better in the end.
In the marine world, on big ship engines, they often re-chrome the liners rather than replacing them. You just need to find the place that does it in your area.
Also, they will build the new chrome surface thick enough to return the bore to the factory size and then properly hone it. They will likely need your pistons to measure.
Finally, I've been told that we have to re-chrome our liners. Apparently they can't strip them and then use Nikasil and have it last. It was recommended to me to have them re-chromed. This is what I was told.
I would suggest googling "cylinder re-chroming" or "cylinder re-plating" or just "cylinder plating." I don't know the terms in your native language, but if you try searching in your country for it, you will find it.
This company has two locations in the UK. You might consider trying them.
http://www.langcourt.com/index.htmSee if you can contact Sjamp van Esch in Eindhoven, The Netherlands. He knows the Nikasil process and would likely know of other plating places or may be able to help you out. I don't have contact info for him, but I'm wondering if he would be in the telephone directory. I read a post that he is working as a plating engineer in Eindhoven.
http://www.finishing.com/219/09.shtmlI also found this company in The Netherlands that does Nikasil plating of cylinders. They will also likely be familiar with re-plating chrome.
