[Amps] Wanted: Delay on Start Timer

[w2cqm at juno.com]

Looking to purchase a 180 second ON START delay timer(s). Can be fixed or adjustable. 8 pin octagonal,faston, or solder type socket OK. Prefer 110VAC, 12VDC/24VDC coil relays. Vintage Potter & Brumfield type OK. High current is not required since it's use is for light duty control circuitry. Can PayPal funds directly from my account from zip 18426 in Pennsylvania. Any help would be appreciated. Ron W2CQM/3
