antique doll stroller and baby buggy

i found these at an antique store here in alaska. i have always wanted one and when i found this i was so thrilled. i collect old dolls and found one that my mom had as a child so i bought the doll stroller to put her doll in since she also said she had one of those. the antique store didnt have much info on them but i thought since my mom had one and the store said they thought they were from the late 40's early 50's that might be correct. im not looking to sell them they are very sentimental for me and i just would like to know more about them like who made them and when. any information would be appreciated.
