These are all known to the hobby but it is still cool to see them lined up together... The back to front line up on the right... M-2332 (two part mold likely 1902 production), U-941d- a stile found only in the Victor dump thus far, U-339a- the big Loop or ring top, common old U-964 (three part mold version with thick base ) There is also a U-441 and a U-670a on the left but those are more ho hum...
