These are a group of six NOS Bosch diesel injector nozzles. Their spec is DN OSD 261, if anybody is still running veg oil these are the preferred nozzles. They are the original spec for the OM 601/2/3 engines but they are used in all the IDI OM 61X engines as well.
These are new old stock, I've had them for at least a dozen years and I picked them up at an old shop the had them for a dozen or more as well. There is a single German made, there are four French made and a single Turkish made. I know there are horror stories about India made but these were all produced before production was moved I suspect.
back when I obtained these the gentleman who sold then to me disturbed the conformal coating on the German, the Turkish, and one of the French nozzles to show me they were as the boxes said. Yeah he was a bit anal and was a German! The other three French nozzles are in sealed boxes unmolested. It's not any problem but it's there.
I'm not sure what good nozzles like these would go for today but if $250 for the six is too much I'm open to reasonable offers.
