Ives 3241 Clipped Pantographs

Hi guys,

I bought a pair of 3241 sets online yesterday, and have noticed in the photos, that the red locomotive has clipped pantographs. I searched on the Ives site and it's showing clipped pantographs as 1926/27/28, but not earlier. Would Ives have used clipped pantographs on earlier engines too?

Here's some details about the engines:

Red -

• Cast-iron frame, with third rail shoes and painted steps
• Cast-iron wheels in red
• Green window frames
• Gold lettering
• Two Clipped pantographs
• No 'R' stamping
• No whistle
• One bell

Green-

• Frame is similar to red 3241
• Wheels are similar to red 3241
• Red window frames
• Silver lettering
•  Two Full size pantographs
• No 'R' stamping
• No whistle
• One bell

Thanks,

Alex
