Rom I think your lack of response is based upon the fact that we in the US do not find lamb's liver. I assume it may be available in some specialty stores, but I have never seen it and I can assure you it not commonly available.
What we routinely can find are beef liver and chicken livers.
Have enjoyed lamb's liver in the UK, but have never had it here.
I think that may explain the dearth of responses.
