J A Henckels 110 7" Cleaver Laminated Carbon Steel Solingen 20 OZ 1950s?

J A Henckels heavy 7" cleaver with a laminated hard steel and mild steel blade (boundary visible on middle of blade), handled with either a walnut or darkened fruitwood (pear?) scales and solid factory made rivets (not pin and disc). 

The blade has a large serif marking and the mid century slightly narrower twins logo. 

An uncommon cleaver, most that turn up have a solid steel blade rather than an extra hard laminated steel edge half. It definitly was a lot of work to grind compared to the steel ones. 

7x2.75" blade 12.25" overall length 20.3 oz
