Re: Johnson Model A Question

[PM T2]

To (try to) answer the original question……. which I believe was restricted to the transom screws and handles, and not to be confoozed with the tiller handle….for clarification purposes, I’ll refer to the transom screw handle thingys as "wing-nuts"

FWIW all my pre-1925 Johnson Light Twins have brass thumbscrews with brass wingnuts on them. Lowest number I have is #765. My highest number 1924 model "A" motor is #16402

My 1925 AB-25 has brass screws, but aluminum wingnuts.

The 1926 A-25 and 1926 P-30 have aluminum screws and aluminum wingnuts.

Given all that, we may be able to at least suggest that the 1922-24 model "A" motors had brass screws & wingnuts, and motors beyond that were given aluminum parts instead.

Sorry, can’t explain your #77XX with aluminum thumbscrews. It might be a replacement transom bracket, or replacement screws/wingnuts. or replacement something.

Regarding getting info out of SIG Leaders – you could always try to get it from them and, if successful, share it here. Otherwise, I’m with Jack, and try to encourage people to find out as much as they can by doing their own research.

Hope this helps.
