Possibly your best source of parts would be a junk Spesco mod.151.
where can i buy parts Kmart
I have a Model 151 in 20ga imported by Spesco. It was Brazilian made. It was purchased in 1960's. Not sure if all were made there or not.
60-100. 100 if perfect.
Spesco did not make firearms. They imported them.
I have one of these and have never seen another

The gun was made in Brazil and would resell under $100. Parts can be found at: http://www.gun-parts.com/brazil/
Maked from 1980's till 1990. From Brasil, CBC. Unexpensive and reliable, good for shot down pigeons or rabbits.
No published sn data.I can say that the Mossberg model 151 semi-auto .22cal rifle was made from 1950-1951 if it is the model 151K.The model 151M was made from 1946-1947.The model 151M(a),151m(b),and 151(c) were made from 1947-1958 and were close to the model 151M with minor changes in the buttplate,and sights.
No much, I think. It's a "out of line" gun (discontinued). You can find out it in some dealers about U$50 . But it's a reliable gun, if in good condition.
