What is this crest? Yorkshire, England 1928

[KGarrad]

If it is Bradford, then the crest should be a boar's head - without it's tongue 
And the supporters should be a black ram and a white Angora goat.

Thanks for all the feedback so far.
Charles was living in Wortley in 1939 but he was still in Normanton in 1928 and the early 1930's and Wortley is more part of Leeds than Bradford.
I have found a version of the old Bradford County Borough crest - this was apparently a badge on the front of a trolley bus - which is also less detailed than the full blown crest (but not as crude as my grandads medal).
I don't know of any connection with Bradford in our family.
I don't think he was particularly religious so Christian Union seems unlikely.
In the same year, 1928, he was Normanton Swimming Club champion and received a similar style but slightly larger medal, possibly by the same jeweller?

Yes, and C is 1928

Heraldry is never an exact science

The actual artwork is left to the individual's expression - just as long as the rules of Heraldry, and the blazon, are followed.

Both the medal and the bus badge can be identified from the blazon:

Arms : Per pale Gules and Azure on a Chevron engrailed between three Bugle Horns stringed Or a Well Sable .

Crest : On a Wreath of the Colours a Boar's Head [sans tongue] erased Or in front of the Trunk of a Tree sprouting proper.

Supporters : On the dexter side a Ram Sable horned Or and gorged with a Wreath of White Roses proper and on the sinister side an Angola Goat Argent horned Or and gorged with a Collar Gules thereon three Roses also Argent.

Motto: 'LABOR OMNIA VINCIT' - Labour overcomes all things

That's what it's meant to be. In layman's terms the arms are divided vertically with one half red and the other half blue, but on the medal they've reversed these below the chevron.

Apart from that, though, the arms are so similar to those of Bradford that I think that must be what they're intended to represent.
