Thanks Blair, that Uberti tip is very handy.
I went with winchester due to the ejection cover spring being of leaf style where the current uberti is a compression spring. Uberti Aust said they did not do a leaf so assumed it was more winchester part orientated. The ejection cover, spring, screw and guide all fit with minor fitting, thankfully.
I do need a rear barrel band so I shall hunt for an Urberti one now with your tip.
You mention Euroarms starting in 1972, I wondered why my serial number was so low. serial No 2010, would have been early in the run, I wonder how many they made?
My barrel actually has [XX9] which is listed as an Italian weapon year number 1973,
If your interested here is part of the extract:
Using Roman Numerials, starting with 1954 as 'X'.
X = 1954
XI = 1955
XII = 1956
XIII = 1957
XIV = 1958
XV = 1959
XVI = 1960
XVII = 1961
XVIII= 1962
XIX = 1963
XX = 1964
...continues without skipping until
XXVI = 1970
Then, for some reason not really explained, they switched to:
XX7 = 1971
XX8 = 1972
XX9 = 1973
Then back to:
XXX = 1974
then a letter
AA=1975
AB=1976
AC=1977
AD=1978
AE=1979
AF=1980
AH=1981 (notice they skip AG)
AI=1982
AL=1983 (skipped AJ and AK)
AM=1984
AN=1985
AP=1986 (skipping AO)
AS=1987 (skiping AQ and AR)
AT=1988
AU=1989
AZ=1990 (skipping AV,AW,AX, and AY)
BA=1991
BB=1992
BC=1993 etc etc
