Pics?
Generally for the strongest jaw, its marine ply- the good (expensive) stuff. Maybe you can get some scraps from a shop that uses a lot of it?
The older WM's had the jaw face doubled and then grooved with the little "V" and if yours will accommodate the extra below I'd recommend that.
As was recently mentioned the dog holes are metric, not inches, but being down under that may not be a big deal?
Wow, I'm glad you jumped in here! I've owned eleven 79-00x Workmates, and seen many more, but this is the first Type 7 I've heard of. Other than the color of the top, can you spot other differences between the two you have? What can you tell us about ownership? Are you the original owner of both? When did you get them?
I spotted a tag on the WM with the lighter colored top indicating it is a Type 7.
Did you look at the bottom surface of the jaws? For the 79-00x models, the model and type are often stamped in ink there.
I spotted a tag on the WM with the lighter colored top indicating it is a Type 7. Not sure what type the WM with the darker colored top is. Anyone know?

Do I have two Irish Workmates?
It was my understanding that all of the blue ones were made in Ireland. And, it does look as though it probably says "Republic of Ireland".
Other than the markings, what differences can you find between them? In the photos, all I can spot is the different rib pattern on the footplate.
Yours is a 79-001 type 6, produced from 1978 into 1979. It should match the second one shown in the pictures on page 55 of this thread in message #1089 from txlonghorn.
Sure learn a lot here on GJ.
I've had one for years, and didn't even realize it until I saw this thread...

Inherited from F-I-L.......use it ALL the time! In use too much to have the time to re-paint!

Wolf,
Any idea what years workmates were made in Ireland?
Different rib pattern, different casting numbers on the H frames (although they are very similar in appearance) and different weight. The WM625 is heavier at 32lbs and the “other one” which is 27lbs. The steel is a little heavier gauge on the WM625. Other than that, almost identical.
The 2nd one was on C/L cheap so I bought it today. I saw it while searching info on the first one. It is a 79-004 type 1 with dual height feature and aluminum cross frame. It even had the original box with it which I thought was kind of cool.
Your second one is a type 6. I found a type 6 to compare it to on eBay. Notice that it has the type number on the bottom surface of the jaw.

Yours has the single layer jaws, the dark orange top, the rubber-bumper secondary feet, the all-plastic handles, and the label on the crossbar matches. The one on eBay has a plywood top, but it's hard to tell from the picture what yours is made of.
Take a careful look at the aluminum riser blocks that connect the wooden jaws to the top of the frame. Are they different between the two?
