[ForSale-Swap] Relay question - again

[WØQFC]

I am still searching for info on a CP CLARE # HG 3056 mercury relay.
I understand that the Hallicrafters HA1 "TO KEYER" used this relay 
(Hallicrafters part # 021-000528). The HA1 schematic/parts list does not 
reveal the coil voltage -  it is used in the pate circuit of V4.
I would like to know the original specs on this relay: coil voltage and 
contact current.
Several fellows have responded to previous post with info, but 
unfortunately, the info was not correct.
Lacking the original specs, can anyone tell me on what voltage the relay 
would operate - the DC resistance of the coil is 598 ohms.
I have spent hours searching the net using various search engines and have 
come up empty.
TIA
