I have no doubt about the RZM marked short dress bayonets? Anyone seen a long one so marked? Wish I knew more about the issue type equipment and bayonets, but some authentic SS markings do seem to appear on such. Etched SS dress bayonets are extremely rare and were undoubtedly special ordered. Is there a period maker catalog that illustrates them. Never seen or heard of such. Probably more than a few fakes of these around, but there do seem to be "legitimate" examples, based on workmanship and other factors.
