Not too long ago, we had a discussion of my 4 1/2 plane. Stanley blade, Stanley style lateral adjust lever, but it was marked M 4 1/2, and nothing else. After a bunch of searching, it turned out to be a Marsh 4 1/2. That same searching also showed that Rockford made identical planes to Marsh, which is nearly indistinguishable from Stanley. I ran across an R 5 on ebay and put it on my watch list. It didn't sell, so the seller lowered the price, and it still didn't sell. Well, the price finally reached $12.75. I couldn't stand it any more and bought it.

Stanley bought out both Marsh and Rockford, and I know Marsh produced quality tools. The Rockford Tool Co. was a sister company to the H.C. Marsh Co. and both companies occupied the same building in Rockford Illinois. It seems that the Rockford planes were furnished with Lakeside blades, though my 4 1/2 Marsh has a Stanley V logo blade. Maybe I'll keep an eye out for a Lakeside blade and cap iron, as these are missing from the R 5 I just bought. But for now, I'll just put in one of my #5 blade and cap irons.
