Newbie with an identification question

Hi guys, I've owned a few bikes over the years, recently sold my first that was a dt50mx, to add to funds for a mortgage.

Now I've got the house, I've found a Tomos moped in one of the out buildings.

I've joined here to see if anyone can "shed" some light on a model/value.

 

cool,
cheap commuting transport
I dont think they are worth much, but working right, you can easily exceed 100mpg.

 

Thats an a3m
Fantastic bikes, hugely underrated.
Value is between 50 pounds and 400.
Parts are cheap and plentiful. Tomoshop.nl treatland and 1977mopeds are great parts sources.
Welcome
