I would venture a quess that Parker reloading implements were made by BGI to Parker specifications. It would be no big deal to tool up if you are already making the basic tools.As far as the Kelsey capper goes Parker held the patent for that and they also owned foundry's. They most likely made those themselves

Mark, I studied TPS carefully and am now convinced that the popular belief that the Parker stamped shot measures, powder measures and combination measures were made by B.G.I.C.O. is wrong. TPS clearly says they were Parker Bros made and were of better quality than other makers.

Most of the Parker marked cleaning accessories were made by BG and there was a close longstanding relationship between the companies, so I think that carried over into forming the misbelief. I have spread the misinformation when asked and I know others have also. Perhaps we can correct that.

Perhaps Dave Suponski will see this also and come to the same conclusion.

I have a Parker Bros. stamped combination measure with ebony handle.

I have both BGI and Parker Bros. reloading tools in my collection. After Bruce got me motivated with his post I sat a spell with both measures. While the Parker Bros. measure has attatching screws for the handle assembly and the adjustment is more positive if I look at the handle profiles and the basic tube forming I would believe they were made by the same company. But this begs the question ...why would two companies very close in proximity and already have a business relationship manufacture the same basic tool? Of course this is just conjecture on my part. What I should do is contact Mr. Waite(one of our past board members)who is a decendant of Marcellus Hartley. Thanks Bruce for getting me off my butt on this one.
