Aerocycle Troxel stamp

[STRADALITE]

All of the Aerocycle Troxel seats I’ve seen have this style stamp on the left.

But I just got one to restore that has the stamp on the right.

Does anyone have another one like this?
Please post a picture if you do.

My 1936 Schwinn motorbike has the stamp on the left-orig to bike. Maybe others can chime in on what is on their bike. Or does somebody have a piece of literature like the Chicago Cycle Supply catalog with that seat showing second type logo. It is reasonable to assume it is 1935/late 1936. The seat made its debut in 1934.

Update: checked on a Troxel long spring seat I have that came off a '37 Colsen(supposedly) and it still has just 'Troxel-patented'.
