Yep they are from a different source, the spigots are solid brass not sure on the mounting plate but this is the shape of the later or earlier original tins, in fact I kept two back for myself, the paint also is a mile off, but I,m guessing they matched the inside of a tin regarding paint.
A spray of Bronze green on the outside and they are as good as the originals........
The scope covers are a bit of a let down, I ordered some of these but they are just a stop gap as far as I,m concerned and would advise anyone looking at them not to bother and go for the better quality repro ones.,
I,ve a job lot going on ebay soon just to get rid of them, think I have about 7 of them.
