I recently acquired a couple of powder slides. From the appearance/style of a given slide can the actual manufacturer be determined?
For example, in the picture the 3.0 Gr BE slide looks like other genuine Star slides that I have, but the 3.9 gr slide isn't made quite the same. Is this a Phelps slide, or is it possible to tell? Are there any known differences in quality or performance for slides not made by Star Machine Works?
