First the name is Jack Sim, not Sims.

I agree with Matt, your pump is a 994, and the 55465 tells me your pump was born in 1951. As someone mentioned above, put your nose very close the the round thing around the reset handle, and the 994 should be stamped in the bezel. You are missing a number of parts so here are some pictures of the pump to help you in your search. http://petrolianacollectibles.com/gb%20992.htm
