need help I.D. some gauges

just bought a small box of misc. gauges from a antique store and wanted some help identifying what they came off of. if anyone can help i would really apriciate it thanks


#1 it's a stewart warner speedo with a trip odometer

 

# 2 this one just says stewart on the back. did stewart merge with warner latter or is this a seperate company altogether?

 

# 3 this one is also a stewart warner

 

# 4 another speedo this one says north east appliance corp. rochester N.Y. on the back

 

# 5 a gas and oil presure gauge, pretty sure it's a pontiac but not sure of the year

 

last one # 6 just a basic 50's era speedo but again not sure what it came from. thanks in advance if anyone can help. there's a couple more but there covered in grease and*****. i think i'm gonna do a hamb auction for some of these once i get them cleaned up and i.d. thanks again
