That was my grandmother's dishwasher, but with a white (lightly textured?) lid.  Hers had the chute type det. dispenser.  She must have discovered the timing-design flaw as she always popped lid and added more detergent after that first fill drained.  Hers had no pressure release/bypass valve on the unicouple so when disconnecting it from the faucet, it would splash water if not covered with a towel/cloth and made it more difficult to release under pressure.  She never used the machine much...it was not kept in the kitchen but in the laundry-utility room just behind the kitchen. 

I think the BOL machine had the impeller, spray arm version was a step up.  Probably an advertised "leader"  model I'd guess.
