2 Iver Johnsons T B revolvers

[fuzebox40]

I just brought home 2 IJ's, one hammer, one hammerless. I'd like to learn the actual age and whatnot of these that I haven't deciphered after searching the other posts. I think they're small frames but I'm only assuming that because they appear noticeably smaller than my one other IJ large frame.

The hammerless, SN B30209 at the 3 usual places (letter coded under grip).
Pats on bottom of grip read June16.96 Aug25.96 T16.04Pats Pending (the T is at begining of second line and perhaps all that is letf visible from "Oct" ?).
Top of barrel, Iver Johnsons Arms & Cycle Works Fitchburg Mass. U.S.A.
No other markings that I see. .32 cal. 5 shot, 4" barrel, coil hmr spring.
I think the rest is in the pics.

The hammer one, with its markings in all the same places, SN P50526.
Only 2 dates on the butt, Pat June16.96 Aug25.96 Pats Pending, (hard to read but I think is correct).
Again name and address at top of barrel, no other markings.
.32 cal. 5 shot, 4' barrel, flat hmr spring.

Hope this is good info for help on these, thanks. Gonna try for 2 pics of each.
