Seiko literature says the representative caliber for all aspects of the 6105A and 6105B is the 6106A, except for the date setting (for that you should refer to the 6145A).
Glad to hear you're keeping it honest with the original dial and hands.
Oh, and hear is a nice color scan of the older guides, if yours' were not of the same quality:
