Raglan "5-inch" Lathe - the upper top slide casting (a picture of this model here). It is not uncommon for this slide to snap in two across the front edge of the T-slot. Machined complete ready to fit - though you have to transfer the gib-strip adjustment screws and, once assembled, drill and tap the holes to secure the feed-screw end plate.The upper section of the Raglan "5-inch" lathe top slide - fully machined and ready to fit. However, you need to transfer the gib-strip adjustment screws and, because the final alignment depends up the fit of the slideways and final adjustment of the gib strip,  drill and tap the holes to locate the cross-feed screw end plate.
