Tank identity ??

(1/3) > >>

friday:
Im trying to identify parts of this bike for an artical Im scratching together .
chassis = 49 - 52- Indian scout , motor = crocker ,  trans = HD predate electra-glide.
fuel tank = looks brit ??
oil tank = brit ??

HD clutch = 37 tooth 2 row that requires 428-2 chain , that requires 2 row motor sprocket for 1" taper motor shaft = pre 1954 HD sprocket  , tin primary case .
trans out put = HD therefore 530 rear chain

usually motor has magneto out front BUT notice there is a tail and head light ?  there fore , there is power or a total loss battery strapped on but not visable thru rear wheel ?? . magneto could be replaced by gen . there was a dizzy also available for there motors , which would need a gen which was driven off stock clutch basket which this is not . it was an autolite clock wise rot.
HD usually had gen off front of motor driven by the timing gears .
motor has 2 separate oil pumps which are the copper pipes up the guts centre .

HD primary has no allowance for dynamo take off drive or pulley
under the tank theres a wire parallel to down tube

front brake lever by his elbow . no shadow of RH lever on tank = no clutch lever therefore LH foot clutch and LH hand change .
bike is resting on the kicker . right above kick spring is where clutch arm is which needs room to move forwards and backwards .
between the blue line , the rear exhaust and above the clutch arm there is a mass fairly well lit but  ....possibly brit dynamo ?    ......more I look its most likely the shifter drum housing / lid
 
Rear hub =  LH sprocket drum ??  brit equivalents ?
49 scout rear axle is straight dia 1/2-20 , any brit equivalents ?

any ideas or theory , feel free to throw it in the mix , there cant be any wrong answers

friday:
heres Paul Bigsby crocker with HD trans with Battery down back and HD tin primary cases but for VL trans which was a crash box . HD synchro box wasnt available at that time
foot clutch hand change

reason for alt trans is the crocker trans case was a part of the frame .
this bike has dizzy mount where the magneto usually goes

mini-me:
No Crockers here but some have crocks-of-shite.

lousy photo but frame could be BSA plunger; oil tank has shades of AMC; forks could be BSA,even Matchless.

If your magneto is dizzy do the bolts up.

R:
That chrome oil tank on the crocker scout looks to be BSA, widely used 1939 into the 60s.
Surprisingly tough to find a good view of one.


You know, I have half a suspicion that frame might be norton.
The plunger units look to be slightly slanted forward, and the central axle mounts look to be alloy,
and the frame tube meeting the plunger casting is higher up, and the plunger business is not waisted in the middle, and the muffler mounting point just ahead of the alloy part are all more Norton than Scout ?

Even the centre of the chrome back rim is painted black, ala 40s Norton ?
That might make the tank Norton too ?  Not impossible, its tough to see the tank cap clearly though, that would make it hinged...

Hopethishelps !

friday:
know what ?
you just might be swinging the right direction

jesus , now I have to go Norton searching . The lady is still alive , Im gonna have to do some asking . I was hoping to be able to do visual research and fill in the gaps with logic what ever that is.
definite crocker rear light .
the seat springs are conical not usual behive .
the bike is leaner towards the camera , leaning on the kicker which also distorts things

pic is late 50s early 60s , brit bike imports were flooding into usa

thanks guys for any info no matter what observations

the way the light hits the rear frame it kindve hi-lites norton features ......

the oil tank definite bsa m20 ish

is there an ignition key next to the front edge of the rear tyre  level with the gear box filler cap ?....

jesus ....time to count spokes over 50% of the rim then approximate  :P   cheers
