Without seeing photos, the only two early chassis with 7 tubes would be a 76 (73) or 77 (77-A).
73 = 25 cycle version of 76
77-A = 25 cycle version of 77
Edit: Ah, you posted some photos as I was typing. Looks to me like a 76 or 73 - volume control on left, local-distance switch on right. The 77 has the volume control on the right and a four-position tone control on the left (no local-distance switch).
