Hello, I have identified 2 of these since I took the photos. At top is a Dessureau Patent Combination Saw Tool. At bottom is an OTC Buick Stuffing Nut Wrench. 2nd from top is clearly stamped, but no maker's mark. 3rd from top has in raised figures H-68??. Thanks, Lou

Reading the patent for the saw tool, it appears it is a combination sawset and sharpening tool for crosscut saws?

Hello, yadda.  Yes , "device for fitting crosscut saws". Saw Set, Jointer, Raker Gauge ,Set Gauge, and Swaging Hammer. All to prep a saw for sharpening. Regards,, Lou

I wonder if Bob has one of these?  He tends to like his multi tools a little more pliery, but this one checks a lot of the boxes for unusual Combination/ Multi Tool.

Could you check the opening on the tappet wrench to ascertain if it is SAE fractional inch sized?

My thoughts is it is for an English built Diesel engine.

Is it marked Herbrand?
