Snatch block
 

Hi boys! Can help me for id this snatch block?
Thanks in advance!

More pictures.

SWL= safe working load.
Unusual that they made the shackle and eye bolt like that.

So........
 

SWL 2 ton capacity with a 7 ton winch.....???

My electric winch at #14,000 on the trailer.....with a double pulley could not pull a cab 13 frozen to the ground....... it actually pulled the 250 Ford and trailer backwards...... until we tied the front of the truck to a ram tank ( at Kars) and jacked individual wheels of the cab 13 to break it fromthe frozen ground/mud but we succeeded..... that why my 250 had an extended cab.....

Lynn, Bob thanks!
No WW2?
No British?
Tons maybe USA poswar?

The second photo in post #2 seems to have "TEST 8 TONS" stamped and the first photo in the same group seems to have a broad arrow.
To me the broad arrow suggests British Commonwealth. Tons can be either long (2240 pounds, more commonly used in Britain) or short (2000 pounds, more commonly used in USA). Both are different to metric tonnes 2204 pounds / 1000 kg.

The snatch block is probably not a Holmes part as an item suppled with their wreckers as those all seem to be 4 digit numbers (But no snatch block listed where I'm looking).
I was also thinking a safe working load of 2 tons was rather light for things as heavy as CMPs. Is it possible the snatch block was designed for earlier, lighter equipment? Or just for moving smaller loads?

Canadian tons and Quebec To-toune.......
 

Robert Bergeron would be familiar with that unit of measure!!!!!!!
