Default tso altimeter

The TSO for altimeter, pressure actuated, sensitive type, is C10b. I
have a Winter 4FGH40 in my sailplane . It was recently returned from
Winter after overhaul with an EASA Form 1. Nowhere on that form, or
in any Winter spec, can I find a statement that the Winter 4FGH40
complies with TSO C10b.

Tim, please give me a reference to a Winter spec that claims TSO C10b
compliance.

My form 1 in this case merely certifies that the work done (overhaul)
was accomplished in accordance with FAR-145 and the work item is
satisfactory for release to service.

As to the OP's question - I know of no requirement for your altimeter
to be TSO compliant. Get your avionics shop to show the regulation,
and if they can't take your work somewhere else.
