Vintage 4" tire, rupp sprocket, tec tank bracket

Iv got a 4.10/3.50-4 tire looks real old id keep it but someone may be looking for somthing original so i thought i put it out there. Says made in holland but no other indication of brand. One sidewall has a grove worn in it and some strange swirl marks. still looks structually sound.
Also a rupp sprocket its 15t 3/4 shaft has 13130 writen in marker on the back. And i have a pull start kinda siezed up and a tc driven for a rupp if your intrested
And lastly a tec tank bracket measures 4.5 hole to hole on the tank
Offers ?

iv got a pair of carlisle double indian heads but the sidewalls are pretty dry rot cracked. I will use them on my own progects. Unless your intrested
