INJECTOR PART NUMBERS?

[The Fiddler]

Hello there,
I wondered if anyone with more knowledge than myself (that'll be all of you then!) knows about the difference in part numbers for Wl-T 2.5Td injectors?
My Bongo started knocking real bad and 3 garages told me it was a big end. But I was convinced it was diesel knock due to a faulty injector, so I bought a couple off Ebay and cracked open each pipe until the knocking stopped to pinpoint the rouge one.
Sure enough, the injector in pot 3 was at fault as replacing it has got the van running as smooth as it ever has.
My query is that the injector I put in is slightly different to the one I took out!
The old one is a 0110, and the replacement one is a 0111 (think it's preceded bu 105078 from Googling Bongo injector part numbers).
Basically the faulty one has a much larger diameter end with a concealed spray nozzle whereas the one I fitted has a smaller diameter end with a visible spray nozzle.
My dilemma is:

Are they both ok?
Will the one I have fitted cause any piston / valve damage in the long term?
Is one a development of the other i.e. an improved design?

I will try and upload a picture of them both together (although I am useless with PCs) (Not too bad with WPCs tho LOL! ;o) - and I'd be ever so grateful for any help or advice.
My instincts are that as the van is running better than ever, things should be ok, but I have seen terrible piston damage on petrol engines due to incorrect spark plugs being fitted and don't want pride to come before a fall here!

Thanks in anticipation,

Fiddlestix.

Thanks Maxheadroom, I had already seen that diagram link posted by missfixit in another thread I browsed. The part number doesn't seem to cross refer to the ones stamped on my injectors and it doesn't show any variants.
I'll try and get the photo uploaded in the hope it clarifies my dilemma!

Thanks,

Fids.
