GP18 Fans

[rogirby]

I need to replace the rearmost fan on a Proto GP18. I think Detail Associates 2003 or 2004 woul be appropriate. Can anyone confirm or suggest an alternative (except Canon as whilst they may be good quality, the prices are silly)
Thanks in advance.

The Detail Associates #2004 is closest to the Proto casting. While I understand the cost of Cannon parts can be high, they still offer the best detail for cooling fans of this type.
