thanks guys,
here's the story behind it which might help explain roy's points:
SWMBO with hairdryer near workbench one morning loses her grip. CRASH! pieces of plastic flying all over. I recovered everything and managed to glue broken parts. The Pak40 survived intact, with breech block missing. I still cannot find it to this day.
Since the breech block was missing, I felt I had nothing left to lose on this model and had a go with the dapples, using this as a lead up to an eventual mottle paint job on my BF-109.
The bad alignment is bad construction, no excuses from me. I've tried to coax it back into alignment, but it was creaking a bit, and I suspect I was close to breaking point. Just a word of warning for guys building this one. DO NOT test fit the rubber tires. They fit. The tires exacerbated the alignment problem because all that test fitting by me pulled them out of shape.
Lessons learnt: NEVER let SWMBO near the workbench.
Don't give up on any model.
Keep my sense of humour.
I posted the model despite it's faults since things like that happen to us all. Rather than leaving it uncompleted or trashing it, salvaging the project could still be a fun experience.
