The 4komas are from the anthology 'Spitfire Classic' by Uchoten. (At the time I was the only one with this book and who uploaded it. These have been translated and edited by me and posted on our Group Blog while ago!

I made an Omake Set featuring all the characters that were featured in the 4Koma's. The images were acquired from a few Spitfire volumes including 'Fundamentals', 'Kaliedascope'.

It's really 2 sets in one!
