That looks a challenge. It looks even worse than the ss100 I'm working on and your 'goat vomit green' is an incentive to get to the primer stage. I shall follow along with interest and I'm sure to pick up loads of car building tips.
Well I've filled and sprayed the body, this in now going to be a street rod, I sprayed the mud guards and the paint reacted weirdly (went all lumpy with holes in it) tried removing the paint with clean spirit (it's an ecologically friendly brush cleaner you wash out with water) and the mud guards melted, I mean to the point it looks like a blob of melted plastic. I've used this stuff before with no trouble.
Well, according to Scalemates, this can be dated back to 1955! Possibly by Airfix, but maybe back to 1953 by Revell! Older than me! It makes you wonder what happened to all those moulds of vintage cars produced by Airfix the Bentley, Bugatti, Darraq, De Dietrich, Lanchester, Ford Model T, Morris Cowley, Mercedes etc etc. I have seen some of these in the original polybag packaging change hands for silly money! ( to me anyway! )
Those old kits certainly pose a challenge, but with a bit of work can make up into nice little replicas. I can remember the old bagged kits from Airfix from way back in the 50's and 60's. There were other manufacturers who made 1/32 scale auto kits from way back. Revell had a small series I think named Highway Pioneers, whilst Gowland and Aurora had 1/32nd scale ranges as well. 1/32 scale seems to have waned over the years except in the slot car racing field. Airfix made nice little Bugatti T35, MG Magnette and Alfa Romeo kits in the 70's and still persist to this day making a limited number of car kits in this scale.
I agree with Dave about some of these bagged kits being sold for silly money by traders, considering that many of these kits were poor anyway. A few years ago at SMW Telford I spotted a Mk 1 Vauxhall Viva on a traders stand that interested me as I passed my test in one. The asking price was £50.00! I may have passed my test in one but also passed on the kit at that ridiculous price. Would not mind betting the trader picked it up as part of a bereaved modellers collection for next to nothing!
