Which barrel?

my original barrel has a cylinder liner.

The outer diameter about the liner (steel)is as great (09/64 inch material thickness), that

between thesecond and third fin only 01/16 inch original cylinder stock available

is present.

I bought another cylinder in Australia about an ES2 from 1930.

This cylinder has also a liner, but 01/16 inch. and

cast iron.

Can me tell some one, if I can take the original cylinder?

Number 47949

thanks
