The final update of season 6, disc 7. Most notable here is the fat boy Clarence, played by Ken Marquis. I have some tiny pics of him before and he also appeared in season 7 (also riding). He wears blue grey bibs (fabric seems quite thin), bib at high position and a rare loop on the rear. I mainly knew a hammer loop which is usually at the side. Pics 1+3 starting at 2h44 (s6e22).
Pic 2 showing Elizabeth in raw denim bibs (appearing a bit lighter in the sun). Bib at low positon. Same episode. She’s laughing at Ben who gets muddy (not in bibs).
Pic 4 showing Jim-Bob and Elizabeth sitting, rear view, both in bibs next to each other, what is quite rare. Elizabeth standing up. She rarely wore raw denim bibs. Also some good rear views of her. Scene pictured at 2h15. There’s also a handsome guest boy actor in ep 21 (Steve Shaw as George Simmons), but not in bibs but regular jeans.
