I have 2 of them and they work well in my 3 SVT 40's. Mine were unmarked . The ones from Gun Parts Corp have or had the big repro. logo on them . Ask them if you can return the if they do not fit . If you work on them to make them fit they may not take them back . Call or e-mail before you buy and ask .Anyone has used repro SVT-40 magazines from Liberty Tree Collectors? Are they good? Looks like their price is much lower than Numrich's, but don't know if they actually work.
