I just bought this frame on Ebay, and was wondering if anyone can tell me the year or model:

It seems somewhat unusual compared to other Grubbs that I have seen in that the pump pegs are under the top tube. The dropouts are 118mm, so it seems the frame would be from 1954-58, when that was common. The frame number appears to be 16324.
