Marples Chisels. The shamrock split proofs are better. To list ALL of these chisels may be difficult, so stick with this site as nobody else is able or.
I stored them in a nice foam lined plastic box, shown, which turned out to be a bad decision - either foam or the plastic outgassed and rusted the chisels all to ****. Change in blade designs helps you date Marples chisels. Good old Marples chisels normally carry a shamrock logo on them not sure about blue chip models though.
Here's a little context to explain why I say that.
Just to wise you up to unscrupulous eBay tool dealers.
I tune them up for the owner/user. It is also a very difficult subject to address, since there were so many chisels/gouges produced by MARPLES, but all had very slight differences (handles). Designed with the user in mind, the Marples ® lineup includes high impact.
