Original Item: Original British military Vickers Medium Machine Gun feed block bodies.  These are marked DP for drill purpose, but show no damage and should be completely serviceable.  IMA has two types of these blocks:  The original, very early block (quite rare) with an integral brass belt support strip, and the modified brass block with a riveted steel belt support strip.  All of the all-brass blocks were supposed to be converted to the brass/steel type, but a very few, somehow escaped the conversion.  This is a once only opportunity to replace the beat-up feed block on your Vickers gun.  Or polish it up and use it for a beautiful and historical paperweight on your desk. This is the Brass & Steel mix.
