I can answer this question now that Ive loaded the film correctly!!! If I wasn't so hasty and had referred to this site - http://www.120folder.com/pearl_iii.htm
- on how to load the film properly I never would have searched high and low on the web about film advance adjustments.... What happened was I didn't wind enough film onto the spool before shooting. Makes sense, not enough girth on the spool to advance the film to the correct length!!
(BTW - I did write the Greg Weber.... no response)
