Scored this (still new) 1971 Zippo at an antique mall for $25 and was thinking of getting a butane insert for it, but wondering if there are any issues with fitment for older Zippos? I'm wondering if the standard size of Zippo has remained the same over time.
On that note, any recommendations for butane pipe inserts are welcome, too!
Thunderbird and Z Plus are I guess the main contenders?
I think I'd prefer one with the flint wheel, but not a deal breaker.
