That’s the sort of fInds I love seeing.
There’ll be someone more knowledgeable than me along to date this but it looks to me to be a 1964 Model Corvette 2. Originally it would have had an impulse starter but it’s been fitted with a 1974 onward zip starter. Most likely after the pawls on the impulse starter wore out, as was common.
I wonder whether they also fitted the decompressor. I suspect that starter may not last as long as it otherwise would if they haven’t. Is it difficult to operate the pull start?
